GRADING
There will be two classroom exams and a final exam worth 25%, 25% and 50% respectively. All exams will be closed book - no calculators. You will be permitted to bring to the final exam one 4"X6" index card with anything written on it, both sides. Grades in excess of 90% on both classroom exams will exempt you from the final exam.

Homework problems (assigned below) will not be counted toward your grade in the course. It is, however, strongly recommended that you work all assigned problems since the exams will be based on the homework assigned. (Otherwise, why assign homework?)

The tentative grading scale is as follows: A: 100 - 90; B: 89 - 80; C: 79 - 70; D: 69 - 60; F: 59 and lower. It is conceiveable that this scale could be modified at the end of the semester, but only to favor the student.

DROPPING THE COURSE
The University policy with respect to dropping the course will be followed. That is, after the drop date, before which a student can drop without predjudice, a student may drop the course with a grade of "excused" only if the student is passing.

PROCEDURE FOR APPEALING PARTIAL CREDIT ON AN EXAM
There is no statute of limitations on appeals. There is, however, a minimum time between the time you receive the graded exam and the time that you submit your appeal, two days after the exam. Your appeal "package" must contain three items:
1. Your graded exam exactly as it was returned to you. DO NOT WRITE ON YOUR GRADED EXAM!
2. On separate paper, the entire problem in question solved correctly - in detail. It must be neat and easy to follow. Your solution must be completely correct for you to be eligible to receive additional credit.
3. On a separate page, explain why your exam problem was not given the credit that you think it deserves. Be specific. Explain what it is that you showed that you knew, but for which you did not receive enough credit.
After your solution (Item #2 above) has been evaluated and judged to be correct, your request for reconsideration (Item #3 above) will be entertained. Note that, since you have, in principle, the entire semester to rework the offending problem, your solution to it (Item #2) must be perfect the first time. In short, you get one shot at the appeal. No throwing garbage at the wall hoping it will stick.
