Grades

Your cumulative score for the semester is a weighted sum of component scores, with the following weights:

• 30%: Homework

• 30%: Final Project

• 20%: Exam 1

• 20%: Exam 2

Grade Cutoffs

Grade cutoffs are approximately as follows, where \(\mu\) is the class average, \(\sigma\) is the standard deviation. These thresholds are not guaranteed, but they rarely change by much.

\[ \begin{align}\begin{aligned}&A+:\min\left(0.99,\mu+1.5\sigma\right), A:\min\left(0.94,\mu+0.5\sigma\right), A-:\min\left(0.90,\mu+0.25\sigma\right)\\&B+:\min\left(0.85,\mu\right), B:\min\left(0.80,\mu-0.75\sigma\right), B-:\min\left(0.75,\mu-\sigma\right)\\&C+:\min\left(0.70,\mu-1.25\sigma\right), C:\min\left(0.65,\mu-2\sigma\right), C-:\min\left(0.60,\mu-2.25\sigma\right)\\&D+:\min\left(0.55,\mu-2.5\sigma\right), D:\min\left(0.50,\mu-2.75\sigma\right), D-:\min\left(0.45,\mu-3\sigma\right)\end{aligned}\end{align} \]
