As long as you read the lecture slides, do the homework, and go to discussions, you should be fine. I stopped going to lecture after the first midterm and did fine. Also, this course is grades are based on how well your peers are doing!",

The course material is also very dense and fairly complex, making it difficult to learn at times. The Exams felt very random and didn't always seem like an accurate test of what I had learned.",

He goes through the slides in detail and makes sure to answer any questions students have. He also does a lot of demonstrations. He definitely made physics bearable for me! Class is easier than phy103 (in my opinion).",
