Here is bit of more info that may help:
His APs are (weighted score) - Gov (99), Precalc(94), Comp Sci Princ (95), Lang/Am Lit (93), World Hist (95), Calc BC(97), Env Sci (100), Statistics (92), US Hist (99), Pshyc (ongoing), Human Geo(on going).
Conversion tools are helpful and will spend some time to convert, not sure why his school doesn’t make it easy by providing converting transcript.
Plus, he has bunch of Honors classes (Chem, Bio, Lit/Comp) and dual enrollment.
I’d say he has very few B’s, no C’s. Mostly A- or A’s.
Yes, he is currently taking 1 credit of Art for UCs. His majors at all three UCs are business/finance.
