@TheGreyKing My D15 was in a similar situation senior year of HS. She had been admitted ED to Pomona which won’t give more than 2 units of credit for AP exams, and she had already taken 5 by then (World History, APUSH, Chemistry, Statistics and Calc BC). Senior year she was taking AP Bio, AP Lit/Comp, AP Gov/Econ and AP Psychology. Fortunately our school didn’t enforce a requirement to take the tests, although her Lit/Comp teacher definitely let her know he didn’t appreciate her skipping the test. She didn’t want to take any, but after much griping and groaning she took the AP Psych test. That ended up being useful for satisfying prerequisites for her Behavioral Economics class.
The interesting thing that I didn’t expect is that, because we sent all scores to the registrar, all six of her AP scores appear on her Pomona transcript. All six scores are listed with two credits awarded but not allocated to any specific AP score. I don’t know how many colleges put AP scores on transcripts, but it’s something to keep in mind when sending scores.
