This a closed book, closed notes exam. Quickly read through all the questions
and then start answering those that you know first. Save others for the end.

The numbers show the points given to each question. They may not add up to
100. Questions come from lectures and reading assignments.

I will stop you in 60 minutes. You will have a 10-minute break. You will then have
15 minutes to discuss the extra credit question as a group. You will have 10 more
minutes to individually write your responses to the extra credit question.

I will tell you when you have ten minutes remaining on the first part of the exam.

Good luck.
