We will have 6 biweekly quizzes on the scheduled dates (1/23, 2/6, 2/27, 3/20, 4/3, and 4/17) in class. We will count only the best five of them for the final grade.  Each quiz takes up to 20 minutes and is based on homework problems and examples presented in class.



There will be six biweekly homework assignments, but only the best five of them will count for the final grade. Assignments should be handed in on the due dates (1/21, 2/4, 2/25, 3/18, 4/1, 4/15). Late assignments will not be accepted.



Grading will be based on the following weighting:

20% Assignments

10% Quizzes

20% Midterm I

20% Midterm II

30% Final exam 

There will be no make-up midterms. If a student has an acceptable excuse for missing the midterms, the weight of the midterms will be shifted to the final. Make-up final exam will be given only under exceptional circumstance, and written, verifiable excuses must be provided



Grading Scale:

0-49%: F, 50-55%: D-, 56-59%: D, 60-62%: D+, 63-65%: C-, 66-72%: C, 73-76%: C+, 77-79%: B-, 80-85%: B, 86-87%: B+, 88-89%: A-, 90-100%: A.
