What are some good prep books or study aids?

It really depends on the textbook you'll be using for your class. I used Cambell's Seventh ed, which was one of the best textbook's I've ever had. If your class is using any of the Cambell books, personally I wouldn't bother getting a bio dictionary- the index and glossary is very compleate, and the entire book is filled with helpful tidbits. I'd try to talk to some people who have already taken the class at your school- find out their opinins on the textbook, and how much it helps out in the long run. Along with my textbook, I used the Cliffs guide. I suggest getting this as well. The only problem that I have with it is that it only covers some of the chapters. However, it explains confusing and tricky things like cellular respiration, photosynthesis and nerve cell conduction in a really simple and understandable manner that is perfect for studying. It also has a very handy lab review section- for this alone I'd recommend getting it. Good luck!

I don't know how helpfful those flashcards would be, but I've always belived that by making your own cards, you can learn the material better.

I'm glad I helped ya out- Bio is a fun class, I'm sure you'll enjoy it.

Wow...I LOVED that book! Anyone with a good sense of humor really will like it. I didn't read it for Bio, though- it was on a reading list for my English 10 honors class a few years ago.

...On those choices, I'm no help to you. I've only used the Cliff's book, and not even heard about the others. Maybe someone like pianogirl or one of the other science-oriented people here will see this and help you....sorry!

Well, it's only helpful to a certain extent. The book only has chapters on chemistry, cells, photosynthesis, respiration, cell division, heredity, molecular genetics, evolution, (very basic) the five kingdoms, plants, animal structure/function, animal reproduction/development, animal behavior, and ecology. These are the areas (I've been told) that the AP tests focus the most on, but there are plenty of sections of Bio that the book simply doesn't cover.
What I liked the most about it was the chapter it has on lab review, and the sample essay and M.C. that it has. It is really good about simplifying complex processes so that you can understand the basics better, which can make the more complex things seem less confusing. It also does a really good job with explaining why such-and-such was the correct answer to a question, be it M.C. or free response. Hope I helped!

Late response I know, but been busy. Finally got a few days off since I gave my book away for the weekend. Nice not to be studying. Anyhow...

I haven't had biology since freshman year sad to say (especially since I'm taking it next semester). I'm not sure which book is the best, but I'd have to say take a look at the topic outline on www.collegeboard.com, then see how much of that is covered by the review books. Then I would look at the books and see which style you like best. Baron usually makes good review books, and Princeton too, but I'm not familiar with science review books, so I can't be sure. You also might want to try contacting your teacher for suggestions.
