Prof Davis was not that bad. She was very good at making the students understand the subject. Her tests were not that hard. I went in feeling really confident but left feeling like I failed, however I did really well on all the tests. The book she uses is really good and if you read all of the text then you'll understand the homework. However, her tests are the worst things ever. You can read all the texts but do horrible on them. She's a horrible multiple choice question writer. The quizzes are very confusing and all the answers seem the same. Besides that, she's very nice and very flexible. I had two midterms on the same day and she let me take mine on a different day. If you take this class, try to get David Diez as a TA. He'll make the quarter A LOT better and help you more than she will. He was the reason why I did so well and he's very concerned that you learn all the material. Read all the chapters, form study groups and communicate with the TA a lot if you want a good grade. Make sure you know your definitions for the tests.
