Department of Math and Computer Science
Computer Science Comprehensive Exam Review

All students taking the exam this spring are welcome. The review will be different than past years. Take a look at the past exams organized by TOPICS:

In the session, the past exams will be discussed conceptually by TOPIC, and some in particular are marked:

Try to do the SELF-STUDY below, that is, read the notes. But even more important is to read and print past exams. But you might want to print them out according to the TOPICS above, especially those marked with *. And you definitely want to print the DS SOLUTION OUTLINE, which are labeled with the name of the function, so you don't need the source question.

• Introduction: 10:30-10:45am
• Data Structure Review: 10:45am-12:30pm
• Break: 12:30-1pm
• Operating Systems Review: 1-3pm
