Absolutely awesome experience. Doing the [exercises] did not feel like homework but it drove home the concepts. Truly wonderful educational experience.
"Professor Babinec did a wonderful job of leading us through this material. It is obvious that he has a passion for this subject. His breadth of knowledge of and experience with cluster analysis added significantly to the course. He gave very helpful answers in the discussion forum! Anuja, our teaching assistant, was very supportive throughout the course as well. The course material was challenging but fulfilling, helping us appreciate the subtleties of cluster analysis rather than thoughtlessly plunge ahead. In summary, this was a very satisfying and useful course."
I am working for Scotiabank/International Banking-Marketing (Toronto-Canada). Since we are manipulating tons of data at the customer level for more than 27 countries, R would be the perfect complement tool (we have been using SAS) for customer analytics. I am new on this R world but I would like to apply it on a daily basis soon.
The Statistics.com courses have helped me a lot, pushing me to the limit and making me learn much more than I expected I could. The knowledge I gained I could immediately leverage in my job ... then eventually led to landing a job in my dream company - Amazon.
I don't believe that I have ever taken a program that more directly impacted my profession as quickly as this program has.
After this course, I have a high level understanding of the various advantages and disadvantages of the commonly used adaptive designs. I will use this information to propose Adaptive Designs at my workplace.
I learned that there are several ways to use bootstrap. The course is an excellent starting point for anyone working with this methodology. I intend to use bootstrap in spatial analysis.
This is the best online course I have ever taken. Very well prepared. Covers a lot of real-life problems. Good job, thank you very much!!
In conjunction with the powerful 'Resampling add-in for Excel' software, resampling methodology seems to be a novel and versatile tool that I expect to frequently use as an adjunct to the more formal established methods of data analysis.
The tools and understanding gained in this course are absolutely vital to the practice of data analytics (at least to an acceptable standard)... Thank you for a great course. I have learned an incredible amount
I felt this course helped me "unwrap" another layer of R, It helped me become a little more comfortable, and less afraid of writing an R program.
I found this course to be very helpful. It wasn't like other courses where you just run example code and change a few things here and there. I learned a lot and have even applied what I've learned in this course to the other course I'm enrolled in currently.... Thank you for the great notes and text!
The course helped me learn Tableau and some of the effective Visualization techniques. I really liked the detailed assignments with hints and steps required to perform some of the tasks.
The book for this course is very good. Everything is explained in a really clear way. Films are great too and help in understanding issues.
I very much enjoyed the Stats 1 and 2 classes, and I think your book and approach really are excellent. I have taken a variety of stats-type classes, including calculus-based probability, but the re-sampling gave me a much more intuitive understanding than any other approach.
I certainly feel that I got my money's worth from this course and this was almost entirely due to the prompt, thoughtful and expert comments of Brady and Andrzej.
I liked the way this course is presented. In every assignment we needed to think logically to produce the required plots and that's what I liked... Thanks for such a wonderful course!
It was great to get a better sense of the Python language. The course gave a great overview of the data analysis and visualization tools.
The lecture notes were clear and concise. The instructor did a great job in covering many different topics in such a short course.
This course definitely adds another dimension to my map visualization capabilities other than just relying on QGIS.
I greatly appreciated learning about SEM from a foremost expert of the subject. I now have a more thorough understanding of SEM from theoretical and practical perspectives.
I found this a very good grounding the the statistical theory, but also there were good discussions about some of the practical issues. The introduction to the various software packages was also very helpful.
Every professor has unique and great qualities in them and the unique and great quality that I found in Prof Anthony Babinec is that he can write pages of explanation for each and every line in the book... He is an awesome professor. He explained each and every doubts we had to the perfection.
I feel this class gave me a much better understanding of how to design experiments and enhanced my statistical vocabulary. One thing I liked about Mr. Babinec's approach was that his written explanations were precise. Once I read and comprehended them, they really helped break down what I was reading in the text that was more understandable, especially by comparing/contrasting terms. Overall, I enjoyed the class and it was well worth the time spent.
Instructor John Verzani provided timely and detailed responses to each and every question posted on the forum. His depth of knowledge in both statistics and R and his passion for teaching are the major contribution to the success of this class!
I took this class out of general curiosity and the fact that it used Python, which is increasingly attractive to me in building my own software tools. To my delighted surprise I found the course to be one of the very best (out of more than 20) I have taken at Statistics.com. It proved a harmonious blend of theory (buttressed by relevant reading and videos by the instructor), focused homework exercises, and training in Python coding. As a result I learned much and enjoyed the process greatly. I was particularly impressed with the instructor's choice of homework assignments, which fascinated me, and with the importance he placed in students writing clear, even elegant, Python code. This is my fifth course using Python at Statistics.com and while I found the other courses quite useful to varying degrees, I never before had an instructor who spent time advising me on the fine details of my actual coding style and suggesting useful improvements. Allan Leis is a seasoned professional, working in the field, and it was a luxury having him cast an experienced gaze on my rudimentary code. It's the kind of thing that would never happen in a MOOC and shows the value of a course such as this.
This course has been a life/work changer for me. Within 2 weeks of taking this class, I was able to produce far more informative plots than I ever had before. I'm inspired to take more classes and learn as much as I can about this wonderful new world. Regarding Statistics.com in general - based on my experience with this course that is, this is a class act online program. A friend recommended it several years ago, but I opted for free MOOCs instead, which haven't worked for me. The small size of the classes, the attention by the instructor, and the assignments bode well for learning. All in all - a great course!
It was perfect, much recommended to anybody wanting to understand the dynamics behind political microtargeting and how it can be applied to business. Many theoretical aspects that were known in the past have been empirically implemented with wonderful exercises of Mr. Ken Strasma.
I have never had an online class before, and I have typically heard bad things about them, so I was shocked when I found out just how easy this course was to manuever. I really liked the format - it allowed me to work at my own pace yet still check in with the teacher and the other students. A really great experience for my first online course.
Both the instructor and the teaching assistant were approachable, helpful, and knowledgeable about the subject matter, and provided constructive feedback about discussion board posts and assignment submissions. The textbook will be a valuable resource for future projects.
Very good instructor!!!!! He interacted meaningfully with students throughout the week. Was open to all questions and Displayed expertise of material. Would take another course with him. Iterative grading was helpful.
The PDF lessons were clear and easy to follow. Thank you for a great course!
Thank you so much Professors for this useful course. I very much liked XLMiner, it is indeed a very simple yet powerful tool
I was really impressed with the clarity, knowledge, engagement level, and patience of the instructor. His contribution in the forums made this the most useful online learning experience I've had (and I've tried a few different venues)
I like the course very much and the material given to us was excellent. I enjoy very much learning about simulations and using Cristal ball software. Also this course has given me valuable information about how to approach a risk analysis, and the software model assistant is very interesting
I found it challenging but also a rewarding experience. After completing this course I am now more confident about undertaking statistical analysis.
It helps me help others analyze their data. Thanks - well worth the money!
Since I started the Epidemiology Statistics class, I've had a much better understanding of the other staffs' concerns.
A very nice introduction to the subject. As someone without any real background in epidemiology, now moving into an area where I need it, this course was very helpful indeed.
This course is a great review of some popular probability distributions and how to test their assumptions. Reviewing the sampling techniques and testing the assumed distributions will help me when I check data and perform regression models.
I appreciated the discussion board feedback as well as comments back on the homework assignments. Both of those things have helped me become a more efficient programmer
Dr. Pruim was an outstanding instructor, extremely knowledgeable, respectful and prompt. This course has given me a strong foundation for continued learning
This is really a fantastic course. The materials were well done and the exercises really helped me develop and apply the concepts. Very, very well done. I will recommend it to my colleagues
I was very impressed with how well Randall Pruim interacted with the class through the discussion forum. I also was pleasantly surprised at how smoothly all the logistical "on-line" issues went. I have already signed up for another course
I like the format of those courses. There is a lot to learn, but it's concentrated on the key points. For somebody working full time it beats a semester-long course.
The course has helped me understand how survival curves and hazard ratios are obtained.
Great pace to the course, nice and concise within 3 weeks, enjoyed the discussions, HW was not too intense and time consuming
It will help me to better understand the methods behind statistical analysis used for conducting research and publishing data. I enjoyed the course. It's really convenient to do assignments on my own time.
As always, professor Everson always provides nice feedback and suggestions to help understand the concepts very well. I hope to take up lot of other courses which she teaches. I am looking forward to many other courses along the way.
All of the courses I have taken through Statistics.com have been excellent in providing understanding of statistical concepts by focusing on the logic and theory behind the equations and formulas, which has allowed me to maximize my learning experience
The feedback from assistant teachers was very helpful, and while I was mostly on target, it helped me see where I needed more help.
I learned more in the past 6 weeks than I did taking a full semester of statistics in college, and 10 weeks of statistics in graduate school
I really like the Statistics.com courses. Just before I signed up for the first course, I had tried to work my way through a couple of different textbooks, and just could not get anything out of them. With this class the clear discussion text, relevant assignment problems, and instructor feedback made it easy to learn. Meena Badade is great at answering student questions with very clear explanations, and Poonam provides excellent feedback on the homework assignments. Thank you both for a great course!
Really solid review of early college level statistics, done in a fairly efficient and practical matter with applications that help to solidify one's understanding of the material. Pleased so far. Good preparatory work for the PASS program.
I now have a better understanding of the foundations of the statistics covered in this module. Although I was familiar with the terms, I now feel more comfortable with discussing the topic! I think the accompanying course text and the support online has been great. I found the course text easy to follow and the in text examples are a good way to test understanding of what you learn as you work through the text.
I enjoyed the course thoroughly. The question-answer sessions (discussions) were really helpful in understanding the concept. I have definitely gained a lot of knowledge about microarray analysis.
Both the instructor and TA were exceptionally prompt in their responses to queries. The comments and suggestions were on point! Thank you for an enjoyable, informative course
I learned a lot of short cuts that I will be grateful to use! I think the instructor and the assistant instructor were great!
This course gave me a solid background on structure of databases and how to use SQL statements to query a database
This was the first class I've taken in a long time, the first online course I've ever taken, and my first statsics.com course. I found it very easy to navigate and was pleasantly surprised at how involved the instructor was in the online discussion. Great class!
Dr. Unwin is FANTASTIC. Wow, I think he is the most hands-on instructor that I've had in the whole PASS program. He truly cares about giving feedback for every student and every thought. That is rare, special and positively remarkable. I truly appreciated it and I'd love to see more courses from Mr. Unwin and spatial analysis--we would all benefit from it
Dave was a fantastic instructor. Lots of personalized feedback. The course was challenging but extremely rewarding. It's made me think about a range of new areas of statistical analysis, which I've found very stimulating
Dr. Unwin is the most engaged instructor I have had yet at Statistics.com. His feedback and involvement was excellent in time given, content provided, and charitable attitude.
The Instructor, Dave Unwin, was great. I have to admit that I had my reservations about taking an online course, but I was pleasantly surprised. Dave obviously put a lot of thought and effort into creating the materials for the course as well as structuring the assignments to give students thoughtful work. He responded to each and every question and was very hands-on.
This was a great class. I learned a lot and enjoyed the format. The lessons, assignments, feedback, and discussions were all informative. I appreciate Professor Unwin's efforts to include references to web sites, journal articles, and books that will be very useful in the future. Thank you!
This is a very interesting course. The readings are very interesting and thought provoking
The course helps me understand different approaches (pros and cons of each approach) in sample size estimates and provides hands-on experience in using various softwares. I highly recommend this course to folks involved in clinical study design
Best course I ever took on Sample Size and Power Determination
I loved the new option to send assignments to the teaching assistant for suggestions before submitting the work to be marked. Poonam was very helpful and provided the right amount of guidance without giving away the right answer. Excellent course!
Wonderful course... I'll never pass a queue again without thinking more about it :). Dr. Ragsdale's book is superb it’s really clear and whenever I had a question it was only a matter of reading more closely to find the answer
I was really impressed with how the homework assignments helped me learn the material. In many stats classes I've taken other places, homework assignments can seem punitive for those who don't understand the material, but this homework seemed to further enhance my learning experience. I would definitely take another class with Dr. Pardoe if I had the opportunity.
One of the best classes I've taken with Statistics.com
The interaction with the lecturer was good, the book is great, the online book material on software is extremely helpful and the lecturer put a lot of effort into a synthesis of the books contents every week. This was by far the best course I took at statistics.com
The course materials are pedagogically well designed. Course administration was efficient. Overall, a pleasant learning experience which is at least as good as any face-to-face course I've attended.
Rasch Applications Part 2 is a wonderful follow-up to the first course. Both courses are well designed and build up over the weeks in a such a manner that they make learning new concepts easy to handle
This course has given me a good understanding of the basics in Rasch analysis. I am very happy that I took this course because I do not think it is possible to just read this kind of information without working with data to get a good understanding of these complex theories and methods.
The instructor Joris Mays was very effective, especially in the discussion board where his feedback was timely, clear and very thorough
This course was extremely helpful in facilitating my understanding of programming in R fundamentals. I feel confident moving forward onto the next section of R programming
Dr. Murrell is a great instructor. His notes and book were great resources. I really appreciated how how he took time to make sure we understood the concepts. He is definitely the best (along with Dr. Verzani from the R stats course) instructor that I've had in all the classes I have taken here at statistics.com
I always wanted to learn R and this was the perfect venue. It forced me to do it and that is what I needed. Tal Galilli was great!! He is very patient and willing to help no matter what our questions were. Overall,great course and I plan to take more.
I have a much better understanding of the *apply functions, as well as using aggregate and xtabs to replicate pivot tables in Excel. This will be very helpful for the type of data analysis work I do
This course is an excellent follow up to the R basic course. A lot of new and helpful material was added and contributed to a more advanced understanding of R programming
Dr Lau's classes are superb as usual
Professor John Verzani is excellent. I used to be thrilled to see his long explanation on the concepts. It was so helpful and makes us love the subject. If you understand the subject, you start loving the subject and this is exactly what I realized and professor's explanation made me start loving R. Assistant Teacher (Shweta Jadhav) really was so helpful. Her feedback, comments were so very valid and felt really blessed to meet and get taught from such wonderful people. Every one at Statistics are such wonderful and nice people. I am really blessed to be part of such an institute :)
Both professor Verzani and the TA's were always ready to answer questions. This is probably the most actively I've ever participated in an online class. I really benefitted from this course and I appreciate all the thought and effort put into making it such a valuable resource for R users!
This course will definitely be used for my work... This course should be called Intro to R for Busy People. I'm really glad I took this course and will recommend it to others.
Thank you John and the TAs!! You've made my fear of R vanish-- the pace of the course definitely helped with building confidence
I took the course to get starting using R, thus I think this will help with my use of statistics in the future. I really think these online courses are great.
I need to know R to perform my job as I am a product manager for a software company that interacts with R. I am now able to understand R scripts and hopefully contribute some of my own. The instructor's videos were great. Just hearing his voice made it more personal. This was my first ever web based course and I really enjoyed it although I had to work hard.
Thank you for the excellent course. I appreciated the timely and detailed responses from Dr. Babinec (for e.g. normalization example when non-numeric predictors are involved). Discussions initiated by other students were also very valuable - esp for PCA and Clusters
Instructor gave good, understandable answers on the board, and several nice summaries of topics we were covering.
I have truly enjoyed this course with Professor Babinec! All the courses I have taken @statistics.com have met my expectations and made me happy because of my professional growth, but this course as well as the course on Likelihood Estimation have surpassed all my expectations!!
The videos are excellent! The information is presented in a very clear and effective way.
Anthony did a great job of answering questions, adding explanations and expanding on ideas. The best teacher I have had at statistics.com so far
The examples used in the class lessons were very helpful and presented real survey problems and their solution for some commonly encountered survey situations
Great course, highly recommended. Ev's role as instructor made a huge difference
I enjoyed the course guidance from Everett. He really helped us to make conceptual sense of the Rasch model
This course has helped me to gain a practical insight into basic/intro test construction and measurement. The course has fueled my desire to increase my understanding of measurement, specifically Rasch and IRT techniques and theories.
This course helped me to learn more about Rasch analysis and Winsteps. I feel that this course taught me the how and why of what I see in my daily work. I like that there was detailed feedback for the assignments. The feedback was really helpful.
This has given me a great overview of Rasch and introduced me to Winsteps which I will use instead of Quest in the future. Thanks, the course was very useful and was very clear and well explained, especially for a beginner like me!
An excellent course. I'd like to thank Mr. Strasma and the Teaching Assistants for a very solid and productive course. I'd love to take additional politically orientated statistics classes
I highly recommend this course for anyone new to R but planning to take GLM, Logistic regression etc as it gives such a great foundation. I am an actuary and all the concepts dealt with in this course are highly applicable to everyday modelling work
I need all the modeling practice I can get in R. I thought this class was very helpful to that end and I plan to take additional courses as a result
The instructor is fantastic and it was a pleasure to interact with him throughout the duration of the course
The course will provide a solid background/springboard to my research in Longitudinal Data Analysis. Questions which required participants to replicate examples in text consolidate learning very much! Instructors were on hand to answer every question that came their way.
I work on projects with multilevel data and this course solidified my understanding of mixed modeling statistical concepts and available analysis packages. I am very happy with this course... The instructors and TA were very responsive and explained the material very clearly. I appreciated having access to archives of previous discussions. This really aided in my learning.
I will be using the methodology of meta-analysis for my dissertation which is on effective schools. This will help me in my work as I am a principal of an elementary school and want to know which strategies have the greatest impact on student achievement
This is an excellent course with a lot covered (beyond expectation). The tutor has been very responsive to queries and comments
Dr. Rothstein is an excellent instructor. I have taught blended classes and know that instructor responses are crucial to the quality of discussion threads. Dr. Rothstein's responses are excellent: informative and kind!
I really enjoyed this course. Great recorded lectures and materials. Questions on the discussion forums were very, very good
The instructor, Dr. LaBudde was highly effective. His written lectures contributed greatly to my understanding and his patient and lengthy answers to my at times overly general questions were extremely informative. It would be hard or impossible to get this information on my own
This is a very well prepared course. The instructor not only pointed out the right book for statisticians but also provided very useful lecture notes that helped a lot
Excellent course! Dr. Smith is very dedicated, always available to answer questions, and makes this online course feel almost face-to-face
I was very anxious about taking this course. The first week was intimidating, but the readings and supplements are amazing... I am walking away really feeling like I have an introductory knowledge of statistics. I appreciated the feedback on assignments. It encouraged me to keep working hard.
This course has been a great help to me. It will lead to a clearer understanding of the data, and to better reports and articles.
This course will help me for preparation for teaching AP stats.
Dave Bock did a great job of listening to all my questions and put very timely and thoughtful responses into his answers
I learned a great deal from the course and recommend it highly for all prospective and current AP Statistics teachers
Feedback on the homework was very comprehensive and detailed, always encouraging. It was a great help for me (thank you very much to the teaching assistant!)
Jen is an amazing instructor. She is open to discussions, knowledgeable and willing to discuss topics. Her you tube videos added substantially to to the course and understanding the material
The Video/ PPT lectures were excellent. Dr. Golbeck and the TA did a great job to ensure a very good environment to learn and obtain feedback. This course is a great addition to statistics.com
Brian Marx is the best teacher I have had. The homework was straight forward and Brian responded to questions on the discussion board in a timely fashion. Thank you Brian for all your effort.
I thought the notes were fantastic - very clear, and interesting. One of the best courses I've ever taken!
I enjoyed this course very much. I was leery of the Excel plug-in, but it worked out well. The study materials were well thought out and effective. The instructor took an active interest in our progress. I would highly recommend this class.
Very interesting course, excellent content. I'm looking forward using these concepts in my business pretty soon
This class was very interesting and practical. I learned how to structure experiments to be able to isolate the effects that the input variables have on the response variable. It was also interesting seeing the application of linear regression analysis in a little different way than I experienced in the linear regression class I took just before this. I appreciated the text and will keep it for reference.
I would recommend this class to anybody (with a basis in probability theory and calculus) who wishes to get acquainted with bayesianism
I learned a great deal from this course. I thought that the instructor, Dr. Congdon, prepared excellent lessons for the course. Dr. Congdon's responses to the questions on the discussion board were clear and very helpful. The TA for this course was also excellent.
I would contend that this Bayesian Computing class (and other Statistics.com classes I've taken) has extremely good value. I have gotten so much education for relatively little expense... the assistant teacher's feedback was extremely helpful.
This course was tough, but immensely satisfying. The instructor's lecture notes were written very clearly and were easy to read
A very nice introduction to Hadoop. Extremely helpful and I appreciate all the work the instructor put into the course. I actually benefitted from the lack of Java specific help since I had to generate code on my own... I wasn't able to ""copy / paste"" which is exactly the kind of environment I needed. I was forced to dig in and found that very rewarding
I thought the course was well organized and I liked the selected readings and text by Stephen Few
Visualizing data interactively will be useful when performing any type of data analysis. Dr. Shmueli always answered questions on the discussion forum quickly and very thoroughly.
I am going to rock the graphics at work! This was an excellent intro to the multiple types of graphics in R, and how and when they can be combined (or not). This can be very confusing, so this type of intro helps to avoid some of the pitfalls and dead ends. It was a fun and interesting class, with lots of opportunity to create graphics and learn new techniques.
I will be working a lot creating customized plots and graphics for reports. This class was crucial for my understanding of graphics in R and how to fully customize the output. Thank you so much, this was truly an amazing course and helped out a lot. Well done!
It helped me immediately with my job. I was able to understand and apply the concepts to a time-series analysis. The R package I was using (vars) required that I read the documentation, which used much of the terminology and concepts in this class. I would have been quite lost without that introduction to the material. This class really stretched my brain! I loved it!
The TA was really helpful and very responsive to questions. Overall the course was a great experience.
The more courses I take at Statistics.com, the more appreciation I have for the smart approach, quality of instructors, assistants, admin and program. Well done and look forward to the continued evolution of this institution!
I can't recommend this class highly enough. Professor Shmueli is an excellent teacher and has written a very clear and practical book. The professor provided good feedback to questions and introduced a wide range of fascinating supplemental information to the course for individuals who want to go deeper. The TA was also excellent with good feedback on the homework
I really liked how the instructors coordinated the course. They are very friendly and very knowledgeable. I found their textbook Practical Spreadsheet Modelling an excellent resource
The modeling techniques learned in this course will greatly assist me in understanding the use of models in the banking industry.
I am very appreciative of the instructor an the TA for their unflagged availability and contribution to this class. It was a very good class and I enjoyed it and would recommend others to take it.
The course was very interesting. It was the first time I've had this level of exposure to data mining. The real life examples and exercises covered during the course helped me to understand the various approaches and techniques presented. It was a terrific course
The theory was clear and well explained; which allowed me to tackle very unfamiliar concepts with relative ease. I feel I now have a really firm foundation on which to build and have been encouraged by this course to keep learning and working towards going even deeper into stats and analysis.
The [instructor] was exceptional at answering unclear issues raised and pointing you to right materials to further help your understanding
This was a very good course. Dr. Indrayan has put together a very good on-line learning package.
Gave me some insights in designing experimental studies, analysis of such eg matched case controls studies, and survial analysis. The course was a master piece. I like the style and I will take more courses.
I really enjoyed this course and found it sufficiently challenging, although well explained and the instructor was very approachable and explained concepts and addressed questions clearly and fairly. Looking forward to Biostats 2!
This was a highly interactive course with a first rank expert in his topic who, fortunately, was also good communicator who likes teaching
This course is well designed and the course materials are simply awesome! The instructor is very knowledgeable in the field and has tons of examples with codes from his website, which is a huge benefit. The focus on programming and practical tips, as opposed to theoretical details, is also a great benefit.
In a nutshell of the 13 Statistics.com courses I have completed to date, this is one of the top three in the intellectual excitement it generated, and the very best taught of all. Prof. Sen has created a jewel of a class,packing an entire semester's work into 4 weeks, but doing so with such intelligence, panache, and elegance that I enjoyed every minute of the many hours I devoted to it. His deft blending of video lectures, outside reading, sample programs, and personal feedback on homework was exemplary. It would have taken me a whole year to learn this material on my own, if I could have done so at all. I cannot praise this course highly enough
This course will help me handle statistical analyses and related consultancy in a correct, professional and intelligent way.
I came into this course knowing the basics of what Structural Equation Modeling could do. I am leaving this course with a whole new understanding of the ways it can be used to answer many different types of research questions. From psychometrics to multi-level modeling, I now feel like I have a whole new bag of tricks in my tool-belt. While I have read books, being able to go through exercises and get feedback was critical. I do not believe I would have come to such an understanding on my own without this course. It was excellent.
I am only beginning to use SEM. Without the course I would have lacked the understanding and confidence to try and use SEM. I now feel confident that I could apply one of the models and use the results for work purposes and publication.
This is very good. The explanation is so clear and practical. The problems are very good. They are not too easy nor too difficult, and they are very practical. Those problems help me to apply the skills in the field
Excellent format, with flexibility to work whenever time is available, and work a bit ahead as needed to work around other committments
