There is actually an AP study book for the new AP French test, it's by REA, and it's called : AP French Language and Culture All Access (Advanced Placement (AP) All Access) [Paperback]. It is currently the only AP study book tailored to the new AP french test.
You can buy it for about 18$ at Amazon.com, and get a free two-day shipping (b/c of a promotion going on). Since I searched and searched for something to help me out with this new test, I just thought any of you guys taking the AP French test would want to know about this. Anyways, hope it helps!
