Back when I was in grade school, E was "Excellent" and U was given for "Unsatisfactory". I believe the grading system we had back then was E, S, A, B, and U (in A,B,C,D,F order). I'm fairly certain on all of those except the D equivalent. They switched back to the traditional letters in junior high.
I'd be inclined to buzz "An F-scored test" for "Things you fail" not because of the F being a synonym for Fail (which it really isn't), but because it isn't an item that falls in the category. You don't fail an F-scored test, you receive an F for failing the test.
