I had him for Math214. His calc classes always took priority to us. He rarely shows up to class on time and always has a bad excuse for why he is late. He gets mad if we dont stay later for him when he is late. Routinely 15 minutes late. Showed up 10 minutes late to exams- nobody finished. Gets smart with the class for his errors. Avoid.

I had Pilachowski for math 220 and math 221. He was funny and good at keeping people's attention. Math 221 (calc 2) is much easier than calc 1. Web assign is great at forcing you to do the homework and really helps to prepare you for the tests. However, Tim's tests tend to be very inconsistent. Also, he can be kinda moody.

Tim would be best described as hard, but fair. His lectures are boring & mediocre at best, and the tests are difficult (but they prepare you well for the final). If you are good at learning independently AND have already taken calc, then I would recommend him - he drops several assignments (not test grades though), & he doesn't assign minus grades.

Late for class and runs through his notes quickly, so you can't really ask questions. But, if you work on your own, do all your homework, and spend a lot of time practicing all the problems, you will do well. Probably, the easiest professor for math.
