Do some courses require prerequisites?
Yes. Courses designated with a “P” in the Time Schedule require prerequisites. Prerequisites may include courses, a minimum test score, or a minimum grade in a prerequisite course. All non-UW students should contact the appropriate academic department before registering to ensure they have met the required prerequisites. If you register for a course that has a prerequisite, the department may elect to drop the course from your schedule if you fail to satisfactorily complete the required prerequisite. In this case, the course will be dropped from your schedule no later than the third calendar day of the quarter. Courses subject to cancellation are identified by the symbol “PX” in the Time Schedule.
