FINAL EXAM
December 14, 2000
Name:_____________________
Rules for Exam:
1. You are allowed one 8.5"x11" sheet of handwritten crib notes. You MUST turn in
your crib notes.
2. Calculators are allowed, but you may not share one.
3. Show your work on numerical problems. Do not expect any credit for a problem if I
cannot logically follow what you have put on your paper.
4. Make sure you include units with each answer. One point will be deducted for each
infraction.
5. Points will be deducted for students that refuse to turn in their exams, when asked

Good Luck and Merry X-mas!
