Reviews of professor Preston Countryman

Rating: 1.0/5, difficulty: 5.0/5
Preston is an okay guy, but he is an AWFUL teacher. I have never taken a class where I genuinely had no clue what was going on. Do not take Solar System Astronomy. Preston teaches very fast, so unless you had good grades in Physics class, you will not get an A in this class.

Overall just not a good teacher

Rating: 4.0/5, difficulty: 3.0/5
Solid professor for physics and is very knowledgeable about the subject matter. At times he is a little disorganized and takes awhile to get things graded but he is also new this year so I bet he will get better. Homework just about every week, 4 tests plus a final (drops lowest grade out of 4 regular tests). Huge emphasis on group work in class.

READ THE TEXTBOOK. Everything in the class he teaches comes directly from that book and I think the book does a better job at explaining the material. Also, the text book is an easy read, but the chapters are a bit long. Don't stress over it though. As long as you read the book, its an easy class to pass.
