Survey the professors
or
Get the actual grades
Explanation:
The first answer will ensure greater accuracy of information because
1) The professors know what the grades for each student are, and
2) The students may have exaggerated their grades to make them look better
The second answer is pretty self-explanatory, and will ensure 100% accuracy because it is the information you seek.
