**Final Exam:** Tuesday, March 16, 8:00-11:00 in MS 5147.

**Literature:**
We are going to use: Friedberg et al. *Linear Algebra*, 4th (Custom UCLA) Edition.

**Grading Policy:**

There will be 9 homework assignments, to be handed in in class on Fridays. Late homework will not be accepted; the lowest score will be dropped. There will also be two midterm exams, and a final exam. Make-up exams will not be given. The homework will account for 20% of the grade, as will each of the midterms; the final will contribute the remaining 40%. If you should miss a midterm due to documented illness or other emergency, the remaining midterm will count for 25% and the final for 55% of the grade. This class will use the myUCLA gradebook facility.

Requests for a regrading will only be considered within 14 calendar days of the due date of the original assignment, and no later than the day before the final. All such requests *must* be directed to the instructor; the TA is not allowed to make changes to grades.
