Credits & Course Info

Note the following information before you register for classes:


A credit is the basic unit of measurement of educational coursework. One credit normally represents either 10 hours of lecture/recitation, or 20-40 hours of laboratory/activity work. Oregon State University operates on a quarter system, therefore credits offered are quarter credits. Three OSU (quarter or term) credits are equal to two semester credits.

Full-time status

To be classified as full time, an undergraduate student must be taking at least 12 credits and a graduate student must be taking at least 9 credits. Students taking fewer credits are considered part time. As well, audited courses do not count towards full-time status.

Maximum credit loads

Fully admitted undergraduates and non-degree seeking students may register for up to 19 credits and graduates up to 16 credits, as an accumulative for the entire summer term. Additional credits may be added, within the guidelines of the academic regulations, by contacting the Registrar's Office.

NOTE: Students are strongly advised to verify their registration and any changes in registration by viewing their schedule on the MyOSU website.

Closed or canceled classes

If all seats are taken in a class or a class has been canceled, you will not be allowed to register for it. We encourage you to have a few alternate classes or sections in mind so that you can complete your registration at that time; or you may try web registration again at a later time (before the term) to add another class.

When you try registering for a closed class, you now can add your name to a waitlist. (NOTE: Not every section has waitlisting.) Visit the registrar's website for more information on waitlisting.

(Multipart courses)

If a class is "linked" to a non-credit lab or recitation, you must register/waitlist for all parts of the course. Web registration will not permit you to register for one part without the other. Likewise, you may not drop one part of a "linked" course; if you do so, the other part will be dropped automatically. If you wish to change one part of a multi-part course, you should drop that part and add the new part at the same time before processing your requested change.

Variable credit classes

If a class is taught for variable credits, for example 1-16 credits, web registration will ask you to enter the correct number of credits for which you wish to enroll at the time of initial registration. If you need to change that number during the add/drop period, you do so by clicking on the link associated with the course and following the prompts to change the credit hours. If the add/drop period has passed you will need to contact the Registrar's Office regarding late registration petition procedures.

Course restrictions

Enrollment in some classes is restricted by course prerequisite, class, major, college, level, degree, or alpha sections. If you do not satisfy the class restrictions, web registration will explain the reason you did not receive the class selected. Generally, departmental requirements on class restrictions are firm. However, if you think your registration merits an exception, please go to the course departmental office.

Special approval

Some classes require consent (approval) of the department. "Departmental approval" will appear in the Schedule of Classes for classes needing this approval. Examples are independent study, projects, research, thesis, reading and conference, music audition, and studio art courses. See the offering department for approval. When you have approval, the department will "clear" you to proceed with web registration; you must then register or add this class to your schedule on your own.
