# 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.
