OP: Just noticed that you took Ap calc AB, because you didn’t test into Calc BC? Along with the B’s in math class, math rigor is not looking as strong relative to your university list. You’re in a highly competitive demographic for CS. The AIME qualifier seems puzzling to me too.
I suggest you add Univ of AZ as suggested earlier. Also suggest that you add some of other Washington state universities as financial backups.
