Comprehensive final exam Dec. 21 Wednesday FINAL EXAM (4:00pm-7:00pm, B&L 109)
(following university final exam schedule)
The grade for the course is computed from the exam grade (54%), the homework grade (10%), and
the final exam grade (36%).
- Homework is collected on the due date, before class, in the classroom.
- No late homework will be accepted without instructor's
permission (a permission must be requested at least 24 hours
before the due date).
- In the final evaluation
the lowest homework score will be
- You may work with other people on the
homework, but you must each write up your solutions separately
(without any written aid). If you work with other people, indicate
who you worked with on your solution.
- All tests are closed book. No text
or notes. No scratch paper allowed. No electronic devices (calculators, phones, computers, etc).
- There will be 3
full-class exams and a final exam. There will be no make-up exams.
