Watch carefully: is she getting 9 hours of sleep? seeing friends? does she spend a lot of time on hw? does she have time to unwind? does she sound stressed?
8 courses including 4 Aps is A LOT .
If she’s gifted (top 1% or higher) it may be just fine. But for 99% kids it’d be a recipe for disaster to have that many classes.
If she seems fine (enough sleep, socialization, fun activities) then all is well.
If she needs to cut down, I’d keep AP Human Geography because it’s a typical freshman “gateway to AP” course.
Out of AP Psychology, APES, and AP CS Principles, I’d remove APES until she’s taken biology and chemistry (ie., as an elective for junior year or senior year) and I’d pick AP CS Principles because it’s in another area of academic interest than Psychology (which is a social science, like Human Geography).
