21-260: Differential Equations
ExamsThe course will have three mid-term exams and a final exam. The mid-term exams will be given on Wednesday, February 20, Wednesady, March 20 and Wednesday, April 24.
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).
HomeworkHomework will be assigned weekly, and turned in at the start of Friday'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.
Homework problems will be grouped according to difficulty. Homework problems marked with a are the easiest problems. Try them for a warmup. If you have difficulties with them, you should reread the section and your class notes more carefully. Problems marked are more difficult, but still straightforward if you keep your wits about you. The problems are the most difficult, and the occasional problem marked will present a challenge to even the brightest students in the class.
Grade ComputationThe 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 GradesLetter 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.
