Registration definitions

Add or drop a course

You may add or drop a course or courses anytime the system is available during the drop/add period for the semester. See the academic calendar for specific dates.

Closed courses

When a section has reached its capacity the system will close that section which prohibits further registrations. Please choose an alternate section or see the department offering the course for alternatives.


Co-requisites are different courses that must be taken during the same semester or session.  For example, CHEM 1110, General Chemistry Lab I, has CHEM 1100, General Chemistry I as a co-requisite.  When registering for courses which are co-requisites, both course reference numbers (CRN’s) must be added at the same time.

Grade mode

The grade mode for most courses can be letter grade, credit/no credit, or audit.  Most courses, except mandatory credit/no credit courses, will default to a letter grade mode.  To change the grade type, register for all courses. Then select “Change class options” and follow the prompts. You may change the grade mode through the drop/add period which is the first five days of each semester or session.


Any holds placed on your student account (money owed, academic dismissal) will  prevent registration. If you do have a hold, the registration system will indicate which office you need to contact for further information on the hold.

Linked courses

Linked courses are different sections of the same course which must be taken during the same semester or session. These often include a lecture/lab combination. For example, MATH 1140 meets twice a week as a large lecture and once a week in a smaller discussion section.  The lecture and the lab both have their own course reference number (CRN), so you must register for both sections at the same time.


Many courses require successful completion of another course prior to registration.  For example, MATH 1160 has MATH 1110 as a prerequisite which means that you need to have passed MATH 1110 with a ‘C’ or better prior to enrolling in MATH 1160.  The registration system does allow registration for a future semester with current enrollment in the prerequisite.

Time conflict

The registration system will not allow you to register in courses which overlap in time.  If this is necessary, contact the department offering the courses for assistance with registration.

Variable credit

When registering for any course that offers variable credit hours, the system will prompt you for the number of credit hours you wish to take.  If you wish to change variable credit hours, select “Change class options” from the registration menu.  You may change variable credit hours through the drop/add period which is the first five days of each semester or session.


A registration feature that allows students add themselves to a waiting list in closed sections of courses through GoWMU. Information on how to waitlist a course.
