What you can do
with those kind of grades is use a 'square-root curve'. Take the square
root of their score times the square root of a perfect score. For tests out
of 100 then a 64 becomes an 80, an 81 becomes 90, etc. If raises and
compresses the scores but still maintains a differential between the high
performers and the low.

Does it mean anything if the grades are clustered together, say around 60?
