Prof. Fitzpatrick is an excellent teacher. Apart from the fact that he delivered the subject matter in a crisp and concise manner, I love his sense of humour too. The style of presentation is really neat. The assignments were excellent too; they very nicely tested one's understanding of the subject and especially in programming, as Prof. Fitzpatrick mentions aptly, one doesn't learn without actually doing it. The automatic grader is quite lovely and rewards you with a beautiful "bwong" if you get a full score :D. I particularly liked the challenging questions - they were what kept me engaged. Profs. Ledeczi and Tairas, and the teaching assistant (Aatish) were all extremely helpful in the discussion forums.
One comment that I'd like to make is that if you're familiar with the basics of programming, it might seem a little slow to you and you might want to pick up coding in MATLAB on your own, since the language is very intuitive. However, Prof. Fitzpatrick gives brilliant insights to code much more efficiently by exploiting the matrix functionality, in turn saving lots of lines of code. Those bits, I believe, could even help mildly experienced programmers.
