# 21-260: Differential Equations

## Exams

The course will have three mid-term exams and a final exam. The mid-term
exams will be given on September 29 (Friday), October 27 (Friday) and
December 1 (Friday).

Tests will be closed book and no calculators. Makeups will not be given.
In case of documented illness or family emergency or documented
University sponsored trips, you will be assigned a grade for the missing
test based on an appropriate section of the final exam (that is, the
appropriate questions on the final exam will count both toward the final
exam score and as a replacement score for the missing test).

## Homework

Homework will be assigned weekly, and turned in at the start of Wednesday's
class. Normally, the homework will include
material covered during the previous week. While this set of problems
will be collected and graded, it should be taken as a minimal selection.
You should test your knowledge by doing other problems in the
appropriate section.
Each student will be allowed to have at most one late homework assignment
during the semester.
The one late homework will be accepted up to seven days after the due date,
with or without excuse,
and without penalty. No other late homeworks will be accepted---even with an
excuse. There will
be absolutely no exceptions to these rules.

## Grading policy

The final grade for the course will be determined by your performance
on the homework, the three midterm exams, and the final exam according
to the following algorithm:
Homework 10%
Midterms 60%
Final exam 30%

## Letter Grades

Letter grades will be assigned according to the following guidelines:

R: < 49, D: 50-64, C: 65-74, B: 75-84, A: > 85

Adjustments to this scheme may be made if there is some operator-error in
making up the tests.

## Cheating

Any cheating on any mid-term or final exam
will, at minimum, result in failure on that test, at maxmum, in
failure for the course. The incident will be reportet to the Dean of
Students per University policy.
Cheating includes, but is not limited to, receiving aid from another student,
giving aid to another student, or use of unauthorized materials.
