==Basic details==

The final exam has 33 questions worth a total of 42 points, on four pages. 15 multiple choice questions, one yes/no, 12 true or false, four short answer, and one multi-part short answer. The test is only a page longer than the midterm and so it shouldn't take you much longer than it it. However, you will have 120 minutes to take it.

While many of the questions are based on questions from the midterm, most of these questions have been changed in some way. Read carefully and consider all options, particularly with the multiple choice questions. Simple pattern matching is a bad strategy!
