This class is a natural science course and has 3 exams which total up to about half of the grade. Students have taken all three of the exams, and it is practically the end of the semester. There are about 20 students in total because there were some drops earlier in the term.
Students don't know the average of each test, and don't know how they're doing relative to the class. I am tempted to reach out directly to ask for exam medians and standard deviations, but am wondering what would be the reasoning. Guessing that it is either for flexibility or because the class size is small. Or it could be teaching style.
Why would a professor not release exam statistics?
Edit: Every other class in the department has been graded on a curve.
