Grades in this course will be based on Homework. We will have approximately 6 sets, a set every 2 weeks. The final 2 sets will be project-like. Any use of written solutions from previous terms is not permitted. If you have access to such solutions, keep them out of reach! Violations will be dealt with severely.
Collaborations with other students are permitted on the first 4 homework sets, as long as you work out the homework by yourself. For the last two sets, we will have a separate policy. Discussions with the TA about the homework are permitted and encouraged.
