next year i am going to take AP European History & AP Human Geography for sure. i don't have enough time in my schedule for AP Art History AND AP Psychology

, so i have to pick one to self-study & one to take as an actual class.
obviously i would like to self-study the easiest one so i get a good grade on the test; which one do you guys think would be te hardest?
btw at my school the pyschology teacher is apparently crazy & nobody likes him! i haven't heard much about art history, but i heard it was hard :P
