Weekly problem sets (50%)
Final exam (50%).
Problem sets should be submitted in hard copy or by email by the start of
class on the day they are due. For email submissions, I prefer PDF,
but plain-text or Word are OK. They will be handed back and
discussed at the recitation
the next day, so they cannot be accepted late.

Solutions to final exam
You may discuss any of the assignments with your classmates (or anyone else)
but all work for all assignments must be
entirely your own. Any sharing or copying of assignments will be
considered cheating. By the rules of the Graduate School of Arts and Science,
I am required to report any incidents of cheating to the department.
My policy is that the first incident of cheating will result in the
student getting a grade of F for the course.
The second incident, by GSAS rules, will result
in expulsion from the University.
