Here is the distribution of scores for the midterm 1. The average is about 58 %, which is OK, but not great. The distribution is almost like a bell curve, but it appears to have a slight bulge at 11 and also another weaker bulge at 17 or 18. I am a bit worried about the points 11 and below. Points 17 and above could be roughly regarded as within the A-/A/A+ range, I think.
