Question about AP Prep books

<p>I'm planning to study ahead and read for AP Psychology during this summer. I look at SAT prep books like the blue book and PR's 11 Practice test books and they always have the same exact contents within the book. I've noticed the same with some AP books but I wasnt sure if they're all like that. What should I do about AP Psych? I might get Barron's 2008 if 09's will be the same as 08's. Also considering Government and AB Calculous. Thoughts?</p>

<p>DEFINITELY get books in the beginning of the year, even if a year out of whatnot. </p>

<p>You'll have the books to study over the summer, for class tests, etc.
I should also warn you there's a period where there are neither 2008 books or 2009 books, so if you want the books, get them</p>

<p>Barron's is okay, but PR is probably the better books you could get for AP. I used a McGraw-Hill 5 Steps to a 5 for APUSH and got a 4. Not bad, but really expected a 5. Then the next year, used PR for Stats and Chem: 5s. I think its just the critical view PR uses which I find useful. I also used PR for ACT: 34. Idk about the collegeboard blue book. Its useful, but it doesnt really teach u how to tackle the SAT. I never used the PR SAT book, but i would guess it's better.</p>
