Ahh, yes. Review books: to use or not to use? Whether or not you use review books while taking classes is really dependent on your curriculum and how you learn. The thing is, the material you are tested on in school tends to be more detailed than the material on the boards. Therefore, you can't rely solely on the review books to get you through your classes. However, the review books are a great resource for pneumonics, tips and hints to help remember complex and tricky material. I think BRS and First Aid are good easy reads. I also found that the Lippincott Pharm review was a good one.
I used review books to varying degrees throughout my first year. In anatomy, I didn't touch BRS until the few days before each test. It was a quick review and the questions at the end really helped cement the details. When I got to the basic sciences (immuno, biochem, micro) I didn't really use the review books. I personally thought Lippincott's biochem was awful and immuno and micro were completely new to me so I read the full textbooks to learn them. I learned Pharm from Lippincott's simply because I thought the lectures were disorganized and incomplete. Anyway, each person is unique and will find them useful to varying degrees. I think it's safe to say, and a lot of people will agree, First Aid, BRS Path and BRS physio are all safe buys. Good luck with everything!!
