Besides the problem sets, there will be a mid-term quiz and a final exam. (One or both might be take-home, or might not.)
If the class is small enough, I may have students present some of the optional topics at the very end.
The problem sets are worth about 33-45% of the grade.
The midterm quiz will be worth about 20-33% of the grade.
The final exam will be worth about 33-40% of the grade.
