+We used a pretty generous grading rubric for this exam. As a result, even though it was harder, the scores are pretty much in line with my expectations of a median of 75% and a deviation of 15%. However, there were quite a few more very low scores (less than 50%) than typical. To adjust for this, we lowered the bottom ends for C and D by quite a bit. We also reviewed a number of exams with scores ranging from 40% to 80% and confirmed that the resultant letter grade appropriately reflected the quality of the work.
