Pre-registration for each term usually begins about a month before the term starts. It's important for students to pre-register for classes to assure they get into the classes they want to attend. Classes do fill up, and some classes are only offered once a year. Early planning is very important.
Note: Each school has its own unique academic calendar and registration time tables. If you are co-enrolled at RCC and SOU, be sure you know the differences in the calendar and time tables that affect you.
