## POLICIES

### Grades

Based on homework (70%), and final exam (30%).

### Homework Policy

Collaboration for solving the homework problems is allowed, however the students should write up the solutions individually. The homework sets should be handed in with a cover sheet that only has the student's first and last names on it, due to privacy policies.
