The determination is based on other posts of the OP.
The OP is proposing to take AP Calc BC, AP Physics 1, AP English Comp and Lit, and AP European History in the same year along with another two APs. These are four of the most difficult AP classes that there are (the high rate of success in AP Calc is entirely due to self selection).
@MWolf thank you for your reply and insight into the difficulty of these classes. In junior year, I plan on taking AP US History, AP Chemistry, and AP English Language & Composition. Would it be better if I chose to take AP Psych. instead of AP European History, and Honors Senior English instead of AP Literature & Composition for senior year? I was originally planning on moving AP Physics 1 to junior year, but I’m unable to, due to some other graduation requirements regarding 2 semesters of visual/fine arts. That would be 5 AP classes, with AP Stats and AP Psych. being one of the easier AP classes.
Rearranging your APs will help a lot, and replacing AP European History with AP Psych will also help. Do not drop AP Literature & Composition.
I would recommend APUSH, AP Psych, AP English Language & Composition, and AP Calc BC during Junior year, and AP Physics C, AP Chem, AP English Lit & Composition, AP Stats, and AP French during Senior year. In general, taking heavy duty courses during Junior year is easier than during Senior year.
Either AP Physics C is easier than AP Physics 1 or 2, because the math of physics and electromagnetics is built on calculus, but Physics 1 and 2, are teaching it using algebra.
If you can take APUSH or AP Psych during 10th grade , that would also help.
