How do I decide the order in which to take courses?

Use the Course Number as a General Guide

Courses numbered in the 10000s and 20000s are appropriate for freshmen and sophomores. This doesn’t mean they are necessarily easy—just that they are courses to consider taking during your first two years. Courses in the 30000s and 40000s have more prerequisites, are more specialized, and are more appropriate for advanced students. This doesn’t mean a sophomore shouldn’t take a 30000-level course or a senior shouldn’t take a 20000 level course, but the numbering does give a general indication about the amount of background expected. Courses in the 50000s are “dual-level” (undergraduate/graduate) and require at least junior standing. Don’t be afraid to try one of these courses. If you have concerns about what will be required, talk with the instructor.

First Take Courses that are Prerequisites for Other Courses

PSY 12000, PSY 20100, and PSY 20300 should all be taken by end of the first semester of your junior and, preferably, by the end of your sophomore year. Note, too, that you must pass MA 15300 (or a more advanced MA course) with a grade of C- or higher before you will be allowed to take PSY 20100.

Take the Advanced Class Soon After Taking its Prerequisites

For example, once you have completed MA 15300, go ahead and take PSY 20100 before your newly acquired mathematics skills have gotten rusty. Then take PSY 20300 before you’ve had time to forget your statistical knowledge.
