C SC 100 Exam 2 Study Guide
The second exam is Wednesday, February 17. It will be closed-book, closed-notes. It is worth 75 points, or 15% of your course grade. You will
have the entire class period to take the exam. The exam will be a combination of multiple choice, matching and short
Note: I hand out two versions of the exam. They differ only in the order of questions.
Classmates on your left and right
will have the other version.
- A complete set of lecture notes is available on the web
http://faculty.otterbein.edu/PSanderson/COMP100/schedule.html. We did not cover every single topic, but you should start by reviewing these.
My exam topics are drawn mainly from the notes.
- Read the textbook. Read the posted lecture
notes for a chapter first, then re-read/review that chapter. There are topics in the book that are not
covered in the notes, and there will be few if any questions over those.
- Questions at the end of each chapter: Multiple Choice and True-False. Work through
these questions. You will see some questions like them on the exam.
- Your journal comments, available at
http://faculty.otterbein.edu/PSanderson/COMP100/journals.html. These are my guide to what resonates with you and I may draw questions from them.
