Does AP Human Geo count as a history class to college admissions and is it considered in core GPA?

I was wondering if APHG counts in core GPA calculation and as a history class/credit?

It counts as social studies/history, and is part of the core GPA.

Yes it does.
It’s a 'gateway to AP ’ class meaning it’ll teach you the level of rigor expected in an upper level AP class and it’ll teach you the format of questions to expect which will make the other social science AP 's much easier.
