The best AP classes to take are AP Literature and AP Calc. For the sciences, you need 5s to receive credit. However, if you take AP Chem/Bio/etc. even if you don't transfer credits, it'll make your freshman classes a lot easier. But if you get a 4 in AP Lit, you get to skip FYC, which is great. Also, for those of you that only took AP Calc AB in high school, if you get a 5, which you probably will, DO NOT LET THE ADVISER PUT YOU IN THE ENGINEERING CALC FOR CALC 2 - unless you're an engineer. If you're Pre-Med or something, it's a pain in the ***. Just take Calc B.
