Fundamentals of Physics II
This class is hard, as you can expect from a physics class. Edwards is a very fair professor as far as phyisics professors go and does a good job of realizing that most of his students won't benefit from the actual knowledge of physics but rather the type of inquiry that physics takes. If you dedicate the time it takes to do well, you won't get blindsided by the quizzes or tests.
Very similar to 161 in terms of grading and course load. I took it because it was required and just had to get through it. The labs and exams were hard so I recommend getting a study group together. Beware, I thought it would be easy since I took high school AP physics but the grading was much harder.
