Midterm exam will be closed book.
One page of your own equations and a
calculator will be allowed. It will cover Chapters 1- 4, 8.4, 9,
and Appendices A.4-A.6 of Kuhn plus all the
lab work you have done. Below are links to useful
equations and an earlier Midterm Exam to
help you review for this one.
