I have so many A-s right now! At my school, A-s, As, and A+s all account for an unweighted 4.0 GPA. I believe that the transcript will show if you have a low A or a high A in each class.
They acknowledge whatever information they can get. An A minus will be viewed differently from an A (even if they don’t recalculate), but having a few A minuses or Bs shouldn’t be a big deal.
