Histograms and percent-to-lettergrade conversions for Exams 1 through 3. The percent-to-lettergrade conversions are based on the guidelines

- the dividing line between B and C is at the mean score, or just below it
- A is more than one standard deviation above the mean (and in my judgment worthy of an A)
- B is the mean to one standard deviation above the mean
- C is the mean to one standard deviation below the mean
- D is between one and two standards deviations below the mean
- F is more than two standard deviations below the mean (and in my judgment below the minimum necessary for a passing grade)

Homework problems are chosen from the textbook, “A First Course in Differential Equations with Modeling Applications”, 9th edition, by Dennis Zill.
