The value attributed to a number varies. For instance, in the French-patterned system, 6.5-10= A, 5-6.5=B, 4-4.9= C, under 4=D, under 2.5= F.
In Israel, AFAIK, 55-64= US C, 65-74= US B, 75+ US A with 88 national honors. So US colleges would know a 92 average would mean a nationally competitive scholar.
@pistcl: beside the questions above, wondering why Brandeis is not on your list. Dickinson and Clark may also be of interest.
