My school puts the numerical grades on the transcript, but I recalculated my GPA a while back with just As, Bs, etc and it ended up being almost exactly the same. I think the ideal transcript would be letters with the pluses and minuses because that rewards students who do more than the minimum to get an A without the stress that every single point matters. I’ve seen kids at my school freak out over a 91 vs a 92, which would be solved with a slightly vaguer system. However, if my school just had the letters without signs on them, I think I would be very frustrated by all the slackers ending up with the same GPA as me despite getting primarily 90s and 91s rather than 94s and 95s.
