@Corinthian his senior courseload includes(probably looks like most students going to Pomona)
AP STAT, AP macro and micro(one class but they prepare for both exams), AP euro history, AP Literature
He has already taken 6 AP classes prior to senior yr to include AP calc AB, AP gov, AP World hx, AP us history, AP lang and comp and AP environmental science.
It sounds like from your post you are saying taking the AP stat test and AP macro/micro could be worthwhile. He does not know his intended major yet but he thinks he is interested in Gov, Economics, English/creative writing
It doesn’t look like you can use any AP credits to get you out of the 5 distribution requirements .
I def. will have him take the SAT subject test in language to try to get out of the foreign language requirement as language is not his forte or interest but is now in this 6th yr of same language starting from middle school and although is not taking AP for foreign language hopefully he can study and get the 650 on the subject test
