## Exam 1

• In-class, written
• Similar to sample exam, but perhaps a bit more writing and a bit less math.
• I'll also probably have at least one question that is directly tied to an in-class or homework activity.

## Studying for the Exam

• Review terms and definitions
• Review activities (in class and homework)
• Do a few more questions to make sure you can do them (and because I may even use some activities as questions).

## Questions and Answers

• I will take questions (and try to give answers) about the sample exam and the handout.
