Exam 3 Score Distribution - Average was 70

How will final grades be assigned?

This is the season where everyone begins to wonder: how the professor will assign final letter grades? The way I do it is this: I will try and adjust the three exams so that they have approximately the same average. This way we can figure out which exam to drop. Then I will apply the formula listed below. Then I will make a plot of the grade distribution and look at it and make a preliminary guess at the grade cuts. Typically, I choose the B/C line at the class average. (Remember that getting average on all three exams, will put you slightly below average after one exam is dropped). Then I look at everyone's scores carefully that are around the lines and decide how to move the lines. The result of this process is the final lines and grades. I will (for the first time) use pluses and minuses, but they don't really count. (See UM policy).

Exam 2

Note: The average on exam 2 was 60 - 10 points below exam 1 . As a result, 10 points will be added when computing grades (and figuring out which exam to drop).
