Letter grades are not provided because your letter grade in this class will be determined by the overall distribution of points at the end of the semester. However, here you can see where your exam 3 score falls within the distribution of exam 3 scores. Since this distribution is almost a perfect bell curve (Gaussian distribution), I would assign a straigh curve to this exam. That would mean a 70 is a solid "C". I would roughly assign letter grades as 60-74.9 is a "C-" to a "C+", 75-89.9 is a "B-" to a "B+", and 90 and above is an "A-" to an "A+". That is 9 "A"s out of 38 students, 12 "B"s, 14 "C"s, and 2 "D"s. This is a reasonable dsitribution of grades. But as I said, those letter grades mean very little at this time. If you scored below 50 on this exam, I would strongly urge you to "modify" your study habits for the final exam.
