I’m preparing for APs and SAT IIs for May. I have a lot of old editions of prep books from when a sibling took the tests a few years back, but they’re all from around 2011-2012. Is it a good idea to use them or are the structures of the tests drastically different? I’m guessing the material tested is the same but I’m not sure if the tests approach questions the same now.
I’m taking AP tests for Chem, Physics C, Computer Science, and Calc BC, and I have old Princeton Review books for these books. I’d rather not buy new books since I already have these, but I also don’t want to be heading off in the wrong direction.
