Grade information may be found on the lms page.

The final grade consists of:

  • Three exams: 25% of course grade each. Tentative exams dates are Feb. 22, Mar. 29, and April 23.
  • Optional Final Exam (during finals week): 25% of course grade. This score can only be used to help your final grade. If your average drops (or you don’t take the exam), the first three exams will be averaged for your final grade.

If you would like to appeal a grade, please submit your request in writing, either through email or on a sheet of paper. Explain in detail why you believe your exam has not been correctly graded. Arguments over how much partial credit you should obtain will not be entertained. If you write your complaint on paper, you can submit either in class or
during office hours. I’ll usually respond in a day or two with a decision.

Guaranteed grades are as follows:

A: 93-100 A-: 90-92 B+: 87-89 B:   82-86 B-: 80-81 C+: 77-79 C:   72-76 C-:  70-71 D+: 67-69 D:  60-66 F:       < 60

There is a possibility of a grade curve at the end of the semester, but this will not be determined until after the final.

Spring 2018 Notes


Suggested Homework












Exam 1 will take place on Feb. 22 in class.  You will be allowed one standard sheet (front and back) for formulas and examples (although you really shouldn’t need it).  The exam will cover all topics up to (and including) Euler equations (problems 17-21 deal with Euler equations in homework 4)



exam1fall18 (Note: this exam does not include questions on inhomogeneous and Euler equations problems, but these are still fair game for next week)
