• 30%: Homework

• 30%: Final Project

• 10%: Exam 1

• 10%: Exam 2

• 20%: Exam 3

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.

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