*Lectures I found to be informative and easy to access on his website. *Homework was frustrating at times, but if Mastering Physics was at fault a TA can fix the problem. *Tests were challenging, but very doable. He allows one to use any non-electronic notes. The majority of Prof. Cowley's classes will say the course was hard, and they will be correct. The main thing that bothers me though is that everyone has a negative reaction to having to work for a grade. It's not Prof. Cowley's job to spoon feed every bit of information to you. He is there to lay a foundation for us to build on. We have to think for ourselves for once. Prof. Cowley can not cover everything in great detail, it is our jobs as students to fill in what is left. If something is difficult to understand on the homework or the class in general there are many options a student can take to remedy this. For one students need to learn how to read a science textbook. If this fails then go to the internet for help, then after that seek help from TA's and staff.
Prof. Cowley is a very unpredictable teacher. He's very good at teaching the material and his midterms are relatively easy and straightforward. But the final was so out of the blue that it put a lot of us in shock. It was HARD. The good news is that with the curve it doesn't affect your grade too much, it seems worse then it really is. Overall i'd have to admit he's one of the better physics prof around
