Auditing Courses

Audit registration permits a student to enroll in a course for no credit and no grade. Course requirements for an audited course will be determined by the course instructor. Audit registration is available to degree-seeking and nondegree-seeking students. The audit registration period runs Monday through Friday of the second full week of classes. See the Academic Calendar for the Audit Registration period.

Students wanting to audit a course must bring a completed Audit Registration form with the instructor’s permission to the Office of the Registrar for registration ( Audit registration is not done online.

Audit courses are assessed instructional fees at the same rate as credit courses. Any changes to an audit registration are subject to the same procedures, deadlines, and special fees as registration changes to regular courses. Upon completion of an audited course, the designation of "AUD" will be recorded on the transcript. The designation of "WAU" will be recorded on the transcript for students who withdraw from an audited course.

Changing Grading Options (S/U, A–F)

All courses registered via the Web are given the A–F or P/N grade option as appropriate. Any changes of the A–F option (to S/U) are done in person at the Office of the Registrar' after completing the appropriate forms. The deadline for these changes is the end of the 7th week of classes.

Closed or Cancelled Courses

When you register on the Web, classes that are closed or canceled will be noted in the "Look-Up Classes to Add" results. We encourage you to have a few alternate courses or sections in mind so that you can complete your registration, or you may try Web registration again at a later time (before the term) to add the closed class.

Course Restrictions

Enrollment in some courses is restricted by class or major or college or level or alpha sections. If you do not satisfy the course restrictions, Web registration will explain the reason you did not receive the course selected. Generally speaking, departmental requirements on course restrictions are firm. However, if you think your registration merits an exception, please contact the course departmental office. See Registration Restrictions in the How to Read the Schedule section.

Departmental Approval of Registration for Courses

Some courses require departmental approval (See the schedule of classes section labeled "Restrictions"). Contact the appropriate department or school to obtain approval prior to registering. The department or school will not register you for the class, but will electronically authorize you to register for the course. You will then need to register for the course on your own.


Students with registration holds will not be permitted to register until holds are cleared. Registrants are informed of holds and are referred to appropriate departments and offices.

Late Registration and Fees

A late registration fee will be assessed for all initial registrations beginning the first day of classes of a term according to the following schedule:

Lectures/Labs/Recitations/Studios (Multi-Part Courses)

If a course lecture is "linked" to a noncredit laboratory or recitation or studio, you must register 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 only one part of a "linked" course; if you do so, the other part will be dropped automatically. If you want to change one part of a multi-part course, you should drop the part and add a new part at the same time before processing your requested changes. Be sure to process the request after specifying the drop and the add.

Major and Minor Changes or Declarations

To change or declare a major or minor, students must complete an Undergraduate Change of Academic Program form available at head advising offices, the Registrar’s website under forms,, or in MyOSU, select Student, then in Student Academic Services, see Forms and select Registrar.

It is essential for students to keep their major and minor information current.

Maximum Credit Loads

Undergraduates may register via the Web for up to 19 credits and graduates up to 16 credits. Additional credits may be added, within the guidelines of the academic regulations, by going to the Office of the Registrar.

Open Courses, Open Sections

Available classes can be found by using the "Look-Up Classes to Add" feature of Web registration. Open and current-to-the-minute section availability also can be checked through the Schedule of Classes.


Prerequisite courses provide the background necessary for successful performance in a course. The university uses an automated check of students' records—including transfer work—at the time of registration to determine whether students have successfully completed the prerequisites for certain courses.

The online schedule of classes lists prerequisites in the "Restrictions" section, which lists all registration restrictions for the class. The online catalog also lists prerequisites in the course descriptions.

  • All prerequisites are required.
  • Prerequisite checking applies to all students regardless of their level, class rank, or college.  

You will be permitted to register only if you have satisfactorily completed or are currently enrolled in the prerequisites for that course. Satisfactory completion may be:

  • A D– grade or higher, or an S or P grade.
  • A test score in the prerequisite. Some chemistry, mathematics, and foreign language courses require a placement test.
  • Accepted transfer work that is considered equivalent to the prerequisite course.
  • Prerequisites will be enforced after grades are processed and students can be disenrolled for not meeting the prerequisites.

Note that you must also meet any other restrictions that the department has placed on the course.

If you have not completed and are not registered for the prerequisite, then you will receive a prerequisite error message when you try to register. You may ask the department offering the course to consider giving you an override for it, which will allow you to register for the course without having first met the prerequisites. If the department declines to give you an override, then you must take the prerequisite in order to register for this course.

Registration Cancellation/Withdrawal from the Term

Your act of registering constitutes your commitment to attend Oregon State University. As a university student, you are both academically and financially responsible for all classes in which you register.

If you want to cancel this commitment and reduce or eliminate tuition charges for the term, you must officially cancel your registration or withdraw from the term (See the Tuition/Fee Reduction Schedule in Tuition and Fees, Drop/Withdraw Refunds section). Failure to pay tuition or to attend classes does not constitute official withdrawal. Students who simply stop attending classes are financially liable for all charges, and may also receive grades of U, N, or F depending on departmental policy.

Registration Cancellation

Prior to the first day of the term, you may cancel your registration using the Web registration system at no charge.

Caution: Do not wait until the last minute to process registration changes via the Web. Although generally available 24 hours per day, the Web online registration system is always down from 11:55 p.m. Friday until 7 a.m. Saturday. If you wait until 10 p.m. or later on a Friday night, you may encounter "system unavailable" messages or busy signals due to many people trying to use the system at the same time.

Automated second week adds will be available beginning midnight of Sunday of the second full week of classes.

Time Conflicts

Web registration will not permit you to schedule two on-campus classes that meet at the same time. If, however, you want to schedule two time-conflicting courses, register for the first course by Web. You must obtain an override from the department offices offering the conflicting courses. Once you have received the override, you can register for the second course using the Web.

Approvals are required.

Transfer Work

If you have transfer credits that you have not yet submitted to OSU, you need to submit official transcripts to the Admissions Office at least four weeks prior to registration opening. Transfer credits are included in your earned credits used in part to determine your priority registration time.

Variable Credit Courses

If a course is taught for variable credits, for example, 1 to 16 credits, Web registration will prompt you to enter the correct number of credits for which you wish to enroll. If you need to change that number later, you may do so via the Web.

Withdrawal from the Term

Beginning with the first day of the term to Friday of Dead Week, you may withdraw from the term by completing the online withdrawal survey available through the Office of the Registrar's website at Students may withdraw from the term for any reason prior to the beginning of finals week. See Academic Regulation 13 for details. See the Tuition/Fee Reduction and Refund Schedule in the Fees and Fee Payment section for information on the financial implications of withdrawing from the term.

Summer Term Withdrawal

Students may withdraw from any courses during Summer term provided they meet the appropriate session deadline to withdraw posted in the Summer Session website at Summer Session students do not need to complete a Withdrawal Survey. Withdrawing from a summer course uses the same procedure used in the other terms:

  1. Login to MyOSU,
  2. Click on the Student tab,
  3. Under Registration Tools, click Add/Drop Classes.
  4. Select the term, enter your PIN number, click Submit.
  5. Select the course you want to withdraw from in the drop-down box.
  6. Click the Submit button at the bottom of the page. The page will reload.
  7. Scroll to the bottom to verify that you have withdrawn from the course. The course status column will show “Withdrawn” and the date of the transaction.

A student who remains enrolled in a course(s) after the Last Day to Withdraw deadline for a session is responsible for completing the course(s) in that session and is not eligible for a term withdrawal for the Summer term. A student who has dropped/withdrawn from all Summer session courses in accordance with posted deadlines will be considered as having withdrawn from the term. Term withdrawal processing will be completed by the Office of the Registrar at the conclusion of the Summer term. Note: Withdrawals resulting from a term withdrawal (as defined in Academic Regulation 13) do not count in the undergraduate 12-class withdrawal limit specified in Academic Regulation 12.

Note that withdrawal from the term does not disqualify you from registering for the next term. If you have any questions, contact the Office of the Registrar, 541-737-4331, B102 Kerr Administration Building.

PELP is designed to enhance the prospect of successful completion of an academic program by allowing a student to arrange a voluntary absence that temporarily suspends their academic work for a period of time. For detailed information please refer to Academic Regulation 13.
