Quiz 3 Results

Each quiz normally consists of 50 multiple choice questions and a perfect score is 50 out of 50. The raw score distribution for the class is as follows:: Median: 32; Mean: 31.7; Standard Deviation: 6.5
Here is the conversion between letter grade and raw score:: A: 39-50; B: 33-38; C: 27-32; D: 22-26; E: 0-21

These grade ranges do not take into account +/- divisions, although these will be used for the final grades. For example, if you consistently fall near the low end of a letter distribution, you will probably receive a '-' and not a solid letter grade (e.g. B- rather than B). The distribution for the class is shown in the figure below.
