meaning of alphabet grades

[keannu]

As I know, each grade's alphabet means the following. If they are wrong, please let me know.

A(4.0) = Ace
B(3.0) = Better
C(2.0) = Common
D(1.0) = Deficient
F(0) = Fail or Failure?

The letters don't stand for words like you have said.

An A is excellent. C is average. B would be above average and D below average. Yes, F is for failure.

I don't know, but I remember hearing it, maybe I'm mistaken.

Aside from "F" for fail, I've never heard these letter to be short for anything at all.

I haven't heard this in the UK either. It sounds like something similar to a backronym to me. The only one I have heard is Fail for F.
