HOMEWORK: Homework is an essential
part of the course, since trying to solve a lot of different
problems on your own is the only way to learn how to come up with
proofs and write them down. Homework will be assigned weekly and
will be collected on Friday in class. Several problems,
chosen at random, will be graded each week. However, it is
recommended to try to solve each of the assigned problems. Two
lowest HW scores will be dropped.
EXAMS AND QUIZZES: Midterms: February 4th (Wednesday)
and March 3rd (Wednesday), in class. Final: March, 22nd (Monday),
8a.m.11a.m.. There will be no makeup exams. Throughout the
semester, there will be several quizzes in the discussion
section. Quiz dates and topics will be announced in advance. One
lowest quiz score will be dropped.
