Self-study AP scores can be problematic for BS/MD programs because the programs really, really want to see a class grade (as well as the course curriculum) because there are knowledge gaps present in the AP exam test material.
An AP CS score (no matter how good it is) is not really something that will impress a BS/MD program.
Also, be aware that not all med schools will accept AP/IB scores in lieu of an actual college level course. Those that do accept AP/IB will expect the student to take additional upper level classes in the subject to demonstrate mastery.
(IOW, med schools feel AP classes/scores offer a weaker preparation compared to an actual college level course in the subject and want the student to demonstrate mastery of the material through additional coursework.
Also med schools dislike using AP scores as a sub for an actual college class because an AP score doesn’t create a grade. A score of 5 is NOT equivalent to an A. It’s more like a P in a P/F class since an AP score doesn’t contribute to a student’s GPA.)
