Exams
There will be two exams during the quarter, and one final at the end of the quarter.  The first exam will be on Friday, April 18th.  The second exam will be on Friday, May 16th.  The final will be on Wednesday, June 11 at the inhuman hour of 8:30 in the morning, lasting until 10:20.  It will be in the same room as the class itself, Smith 405.

The exams will be closed everything.  No books, no notes, no calculators.  Take comfort in that I plan on including a table of Laplace transforms with the final.
