Grades are assigned as follows:

- Each student is assigned a percentage score, where 80% of the grade comes from homework assignments and 20% comes from the final exam grade.
- To convert from scores to grade points, we use a three-point "curve":
- The median score maps to a grade of 3.0
- Half of the median score maps to a grade of 0.8.
- The 95th percentile score maps to a grade of 4.0.
