21-260: Differential Equations


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 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.


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.
