Exams

There will be two midterms and a three hour final exam. Mark the midterm dates on your calendar now.

  • Midterm 1 will be in class on Wednesday 2/28.
    • You are allowed a one page notesheet, front and back, so that you don’t need to memorize formulas. Put some time into it – deciding what to put on the note sheet is a very useful study process!
  • Midterm 2 will be in class on Wednesday 4/10.
    • You are allowed a one page notesheet, front and back, so that you don’t need to memorize formulas. Put some time into it – deciding what to put on the note sheet is a very useful study process!
    • The exam is not cumulative – covered material begins with the first topic not covered on Midterm 1.
  • The final exam date is scheduled by the registar, and will be posted here when it is determined.
