AP Test Format Changes

<p>So for my junior year, I'm planning on taking:</p>

<p>AP Biology- Cliff's
AP Calculus AB- PR
AP Chemistry- PR
AP English Language and Composition- Cliff's
AP Japanese- n/a</p>

<p>I know they're changing the AP Biology curriculum for the 2012-2013 school year so I was wondering if there were any changes in the format of these tests or books within the last 5 years. I'm on a really tight budget right now so I'm trying to save as much money as possible and spending $10 or more on each book when I can be spending much less for an identical book would be really illogical. Also, if there are better alternative review books than what I've listed above, please let me know and I'll be sure to check it out! Thanks so much! ^-^</p>
