First Midterm Exam: Wed, Feb. 28, 2007

The exam will be in class, and you will have 50 minutes to complete it. It will be closed book, closed notes, and no discussions allowed with class mates during the exam.

Here is a list of topics that you should be able to explain or use in a program. Understanding these topics well will help you do well on the exams.

This is a guide, not a guarantee. I intend for it to help you, but questions on the exam can come from any material we have studied in this class.
