Do colleges calculate by letter grades or numerical grades?

Say i get straight A’s, but my school only calculates for the average of the last quarter which can range from 90-93 only. Will they care more about the straight A’s or the fact that they’re not high?

There are dozens and dozens of marking systems. They recalculate according to serve their own needs. They’re not going to strain out your 93=A vs. someone else who has a 98=A. You’re worrying over nothing.

Bingo. Each college is different; some don’t recalculate at all. Regardless, there is nothing you can do about it. Focus your energies on things you can affect.
