ASTR 110
Introduction to Astronomy

As usual, 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, you can see where you fall within that distribution at this time. Recall that your lowest midterm exam score of the four will be dropped in the computation of your total points in the class. In my grading system, those students near the class average usually end up with a grade in the low "B" range. The average is 71 and the std dev is 14.7. According to the curve I usually apply, for this exam score distribution, I would roughly assign letter grades as 55.0-69.9 is a "C", 70.0-84.9 is a "B", and 85 and above is an "A". This is identical to the exam 3 and the exam 4 distributions. But as I said, those letter grades mean very little at this time. If you are below 40, I would consider this an "F".
