(Test 1 Covers pages 1-40 of the lecture notes and the corresponding portions of the text.)

(Test 2 Covers pages 41-87 of the lecture notes and the corresponding portions of the text.)

(Test 3 Covers pages 88-134 of the lecture notes and the corresponding portions of the text.)

Bonus points can be earned for correcting errors of a typographical nature. Also particularly insightful questions in lecture may earn bonus points. The points are weighted with the tests. For example, if you earned 5 bonus points then you could change a 95 test grade to a 100 effectively.
