I have 2 Bs freshman year and 1 B sophomore year, but all A’s junior year. All throughout high school I had the most challenging courseload available, with the exception of 1 honors class I didn’t take freshman year. Moreover, I also have “extenuating circumstances” that resulted in those 2 Bs freshman year, as well as some sophomore year (although I don’t know if that will just make me sound whiny or not, but it’s the truth).
My ECs are not spectacular, they’re probably more average for a T20 applicant. Retaking the ACT next Saturday and aiming for a 35.
