Registration Basics

Students will receive a  Registrar's Office email detailing when they can register, or they can login to MyOSU, click on "Student" tab, and clicking on "View Priority Registration Status" once upcoming dates are posted.  Priority registration is divided into two phases. Students can register for up to 16 credits in phase I and up to 19 credits in phase II, though science majors generally take 15-16 credits.  Waitlisting of courses is only available in Phase II.

Students need to schedule an advising appointment any term they need a new registration PIN (see below).  Students will need to plan ahead to insure an advising meeting before their registration date. Students with holds (listed at the top of the MyDegrees Checklist with a phone contact) will not be able to register until holds are addressed, and students can review the information on student holds for more details. 

  • New students:
    • New Corvallis campus students must attend a START orientation to receive advising and their registration PIN. 
    • New Ecampus students must contact Ecampus student services at or 800-667-1465 (option 1) to set up an their online orientation. Once the online orientation is completed Ecampus students meet for advising and their registration PIN.
  • First year students, NCAA athletes and students receiving veterans benefits must meet for advising each term they need a registration PIN. 
  • Sophomores and higher in Biology or Zoology need a new registration PIN each academic year and generally meet in winter term for advising to receive it (see advising appointment website).

Registration Holds 

Review the top block of MyDegrees (just below your ID number and name) to see if you have holds listed that might interfere with registration. You can review the common registration holds website for more information, or use the email listed at the top of MyDegrees to ask for more information on how to resolve listed holds.

Errors and Overrides

Review the common registration errors to see what might be causing any errors you receive when trying to register. The Science Success Center (Kidder 109) is open daily to assist with registration Corvallis campus students. Ecampus student services at or 800-667-1465 (option 1) can assist Ecampus students. If you are having trouble registering for a course required to graduate the next term, contact your advisor. If you cannot enroll in a class you believe you meet the pre-requisites for, contact the department offering the course (see below). You will generally need to share documentation or a transcript for transfer coursework or test scores that relate to enforced prerequisites. In some cases a syllabus will also be required.
