The purpose of AP courses is, first and foremost, to challenge yourself while getting college credit. As yourself, “will this credit be useful for me in the future?”. “Will I have time to properly apply?”.
I took 7 my senior year (English Lit, Bio, Calc BC, Physics, Micro/Macro Econ, Spanish). Ended up fine, got into college with all of tuition paid etc. But I took them because I understood how the courseload would be, because my parents and counselor felt I could handle it, and because I had a drive to understand each of those subjects and get credit. If you lack one of those, I might advise not to.
