The ranges of grades are below. I am not breaking up grades into "B+" or "A-". Instead, I simply break them up into ABCD, and use those scores to calculate your final scores. When I get the final scores, I will break up the B's into A-/B+/B, and the C's into B-/C+/C.
Also, since this exam was so hard, I will be flexible about its weight on the final grade. For example, if you nail the final AND your lab grades are good, I will minimize the impact of this exam on your final score.
This is a Tukey Plot, which has lines to the max and min, yellow box denoting the 1st and 3rd quartiles, hash marks at the median, and dot at the mean.
In the "answers and grading", there are histograms of scores for each question.
