i went to a public magnet K-12, and we didn't have letter grades until 6th grade. in elementary school, we had report cards but it was just E-S-N (excellent, satisfactory, needs improvement).
i'm sure the teacher gives everyone all A's, but it's gay and unnecessary at such a young age.
numeric grades seem like way less pressure. we didnt even have +/-; just letters. i got straight A's; no B's. had several close calls, and the consequences of one or two B's vs a A could have put me into some ttt instead of an ivy. very nerve-wracking
