Does AP CompSci A count towards core GPA?
If you mean the GPA your school calculates for you, then no one on this forum would have any idea. Ask a teacher.
I’m talking about most colleges…
I want to know how much it affects my GPA for admissions.
Colleges which recalculate grades may each have different policies on what courses are counted. It is likely that most will see CS as an academic elective to be counted, but if you really want to know the answer, look up each college’s web site and ask directly if the answer is not there.
