The Graduate School has developed a quick reference guide to help you quickly access the information you need about semesters and graduate student credit hours, GA appointments, enrollment, etc. It is based it on questions received from graduate students, staff and faculty.

The PDF is available here:

Or it can be accessed from the semester conversion page on the graduate school website at:
