Grading
20% Midterm #1
25% Midterm #2
30% Final exam. A one-hour final exam, the last day of class, just like all the other tests. All are cumulative but tend to emphasize recent material.
25% Homework. HW is intended for learning. The tests are like the HW. Don't count on HW to "pull your grade up". Your grade depends mostly on tests (assuming you diligently do the HW)
