Exams
================================================================

Exams will be held during the regular lecture hour.  Exams will be
closed-book.  You will be permitted one sheet of 8.5x11 paper, with
handwritten notes on both sides.  Calculators and computers are not
allowed.

* On-line section: if you're in the online section, we will proctor
  you via zoom.  The exam will be made available to you, on
  Gradescope, at the start of the exam hour.  One of the course staff
  will watch you over zoom while you take the exam, then you'll
  photograph your answers, and upload the result to Gradescope.

* Conflict exam: if you have a time conflict, please make arrangements
  at least one week prior to the regular exam.

* The order and structure of this course varies quite a lot from year
  to year, so past exams are a much less reliable study guide than the
  homework.  Nevertheless, past exams will be made available to you on
  this page.
