There will be 4 exams totally (currently planned for Sept 13, mid Oct, mid Nov and Dec 11). These are two-hour, in-class exams (roughly once a month) and a FINAL exam during final exam week (Dec 11). All tests will by default be at least comprehensive of material covered until that point in that course.
Each test contributes to 25% of your final grade.
Sample exams and their solutions may be posted or gone over in class during the exam review sessions.
