Special topics courses (X99), like blanket-numbered courses (X01-X10), may be repeated without limit by students. This is an "automatic" feature for X99 courses. Further, it is implied, but not monitored centrally, that the course content is different each time the student takes the course (unless the student is retaking the course to replace a grade as specified under Academic Regulation 20). Each academic unit monitors the repeatability characteristic of X99 courses to avoid abuse of this feature by repeating the same course over and over again.
Unless there is a specific limit placed on the number of times an X99 course may be taken, special topics courses are encoded with "999" in the credit field of Banner, allowing for indefinite repeatability capacity of that particular topics course.
Special Topics (e.g., X99) courses require a New Course Proposal to become an established course but do not require a syllabus.
