"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."

"I know I am not the perfect student but I really am learning an awful lot and absolutely adore this module [Resampling Methods]. But it doesn't matter how I am doing, I still know I have already learnt a lot about something that I knew nothing about. Thank you for this opportunity and all the support received so far.”
