I'm a junior in high school and I am also taking APUSH, lots of fun especially since my teacher just lectures with no notes on the board or anything. Also I had trouble with AP Calc since I took last year, really the only hard part is that normally it isn't that bad but if you study (I didn't) you should be fine. and yeah no way am I taking AP Lit next year my grammar and writing skills are shit, although prob will take AP Comp Sci, AP Psych, or AP stats, maybe all three depends on how scheduling goes.
