for world history, AP book is fine but i recommend you to also look at SAT books cuz there are tiny differences such as that SAT concentrates more on the details. i dont know bout French but i think for math2C, Barrons is fine. some ppl say that Barrons is unnecessarily hard but i pretty much liked the *depth* of the Barrons book (only for math2Cs cuz math2c exams are getting harder each year) Barrons is comprehensible and especially good at some parts including the function part and ellipses, hyperbolas, etc.
just scan through TPR and finish up w/ Barrons.
good luck
