I was wondering how often new review books are released for AP exams. Would it be stupid to order a previous edition of a book (probably a Barron's) right now so I could start studying as early as possible? I'm just not sure when or if new books are published every year...but it would make sense because exams are modified every year.
Last year I put studying off for way too long, and I'd like to be better prepared. I'm intending on taking the Calc BC test, even though I'm only in AB, so it's vital to buy a book early on. But how long should I wait (if I should wait) for a new version? Will it even matter in the end? I'm assuming the content is always about the same.
I'm planning on buying review books for the following AP courses:
Statistics
Calculus BC
Art History
So, for which subjects should it be okay to purchase an older version of a review book, and for which should I wait?
