I think the point that needs to be made is that AP courses will not be the most rigorous options available at BS and will certainly not be the most engaging or interesting or taught by the best teachers. Nor are they necessary in order to score 4s and 5s on the exams. Also, the colleges that know these schools surely wonder why any kid took them over the better options available at that BS. No argument that AP scores can be useful at some colleges, so a student can and should sit for any exam that could provide a benefit but, IMO, the courses are a waste of BS time and money. Why not just stay home and take a boatload of APs at LPS if those courses are so attractive? If any BS says that their AP curriculum is their most rigorous, that school would definitely come off my list.
BTW: For anyone concerned that the regular or honors BS curriculum may not translate well to a particular AP exam, for one class where that was a potential issue (can’t remember which one), our son’s teacher held two (optional) one-hour evening sessions to go over that “translation.” Our son said it was informative but unnecessary. He got 5s on four of the AP exams he sat for but was unable to use those scores at most of the colleges he applied to.
