.

**Policies:**
- No late homework will be accepted.
- The grade will be based on 40% homework, 20% midterm, 40% final.
- This class will use the myUCLA gradebook facility.
- Requests for re-grading will only be considered within 14 calendar days of the due date of the original assignment or midterm and no later than the day before the final.
All such requests are to be directed to the instructor; the TA may not make changes to the grades.
- A grade of 'F' will be assigned to any student who misses the final. Incompletes are reserved for those who have completed all of the work for the class, including the midterm,
but who, for a legitimate, documented reason, miss the final.
- Use of electronics is strongly discouraged during class.
- Come to office hours!
