I moved to a new school and it is required that i take physical science along with chemistry in one year. I need to take physical science because i didn't take it in my old school, and in order to fulfill graduation needs i have to take it. Other than that i plan on taking AP Psychology and AP Environmental Science (note, it's my first time taking AP courses), so that would mean id be taking 4 science courses in one year. I have either that choice or I can self-study AP Comparative Government and take AP psychology with the school then take AP Environmental Science next year as an online AP course. Anyways what I mean to ask is; is taking the four science courses in a year too much on my plate. And which choice is better; self study AP Comparative Gov and take AP Psychology with the school, or take both AP Psychology And AP Environmental science in one year( AP Psych with school and AP Environmental Science online). And know that id also be studying for SAT Subject tests and the SATs.
