Finding Courses

Need to find courses from current or past terms? Here are some resources to meet that need.

Prerequisite Enforcement

Enforcement of prerequisites is a powerful tool for managing your courses and setting up students to succeed in a course. Learn about how to enforce prerequisites for your course.

Priority Registration

Registration occurs in two phases. Students are given access to each phase of registration in batches according to their student status and earned credit hours. A general overview of the priority registration schedule is available on this website. Detailed information about your date and time for registration is available via MyOSU: click on Student tab and under Registration Tools select View Registration Priority Status.

Restriction Overrides

Courses may be restricted in many ways; prerequisites, corequisites, majors/minors/options, college, class standing and others. Restrictions are displayed in the class schedule. The ability to make exceptions to these restrictions lies with the department offering the course. Instructions for providing exceptions is provided in this section.

Tuition & Fee Payment

Students enrolled in courses beyond the end of the add/drop period are responsible for at least a portion of the applicable tuition and fees.


Departments can choose to use electronic waitlisting on course sections. Review the provided information to learn more about how this tool can be used to manage enrollment in courses.

Dates & Deadlines

The academic calendar defines the dates and deadlines for registration transactions within a given term. You may use this calendar to view dates and deadlines for different terms. Please refer to this calendar often.

FAQs: Fall Term Start, Tuition Refund, and Drop/Withdraw Dates

Start Date Related:

Q: Why is the fall quarter starting two days early when Veterans Day is only one day?

A: Due to the loss of class time for multiple holidays observed, Veterans Day and Thanksgiving Day, the OSU academic calendar for fall term was changed for all campuses. The first day of class will now take place during Welcome Week. The following week will officially be referred to as Week 1. These changes were necessary to both honor veterans and to maintain the number of class days in the term.


Q: What is a Welcome Week and is it only for incoming freshmen?

A: Welcome Week includes events that go on for the new and continuing students at OSU.


Q: Are winter and spring quarter start dates changed?

A: No, only the fall term start date was changed. Other term start dates remain the same as before.


Q: Is Welcome Week considered the first week of the fall term?

A: No, the first full week of the quarter is considered the first week of the quarter. For fall term, it is the first full week after the first day of fall classes.

Tuition Refund Related:

Q: When is the last day to receive a 100% tuition refund according to the new refund deadlines?

A: Last day to drop a class and receive a 100% tuition refund is on Sunday, 11:55 p.m., after the first full week of classes.


Q: When is the last day to receive a 50% tuition refund for classes I withdrew from?

A: Last day to withdraw from a class and receive a 50% tuition refund is Sunday, 11:55 p.m., after the third full week of classes.


Q: Are there any other tuition refund deadline tiers besides 100% and 50%?

A: No, there are only 2 tiers to tuition refund: 100% and 50%.


Q: Why did the refund periods change?

A: The new pro-rated tuition period now aligns with the new deadlines. For unexpected individual circumstances, the tuition appeal process will still be available.

Add/Drop/Withdraw Date Related:

Q: Why did the date change for drop and withdraw deadlines?

A: The shorter time frame encourages student success by solidifying schedules earlier in the term and increasing time in class.


Q: What happens if I want drop a class during week two?

A: W grade will be recorded on your transcript if you withdraw from a class starting Monday of the second full week onwards. 


Q: What other deadlines around registration have changes?

A: The changes are around drop and withdraw dates. No changes have been made to the course add deadline. To view all term dates, please visit the Academic Calendar in the Office of the Registrar's website.


Q: I get an error message when I try to add during week 2, what is happening?

A: You need instructor permission and a departmental override to add a course during week 2. Please contact the department offering the course for assistance.


Q: What do I do once permission is received?

A: You should register for the class as usual through Online Services.

Finding Courses

The first step to furthering your education is to find the course(s) that you want or need to enroll in. There are a number of tools to help you find courses that will meet your needs.

Search for classes via MyOSU.

You may access the Class Search feature through your MyOSU account to search for courses for terms that are open to registration. (Steps: Login to MyOSU, click Student tab, under Registration Tools click on Look Up Classes, then follow the directions.) Once you find a course you wish to enroll in you can add it to your worksheet and keep searching or you can submit the change immediately and be enrolled in the course immediately if there are no impediments. For a more detailed explanation of how to search for courses from within the Registration menu view the Adding a Course video tutorial.

Search for courses using the online Schedule of Classes

Using the online schedule of classes you can search class listings in several ways. You can define your criteria in the Search All Schedules of Classes. If you know you are looking for something more specific you can begin your search in a specific subsection such as Baccalaureate Core Schedules or Undergraduate Schedules by Subject. Once you’ve defined your criteria and located the course/courses that you are interested in make note of the CRN for registration purposes.

Need to find a baccalaureate core course?

Watch our Searching for Baccalaureate Core Classes Video Tutorial or go straight to the baccalaureate core courses section of the general catalog.

Do you have concerns about building accessibility?

Visit the campus accessibility site maintained by Disability Access Services and learn the about the accessibility of buildings on campus.

Interested in taking an online course?

Visit Ecampus to find out more information about online courses.

Do you need to search for a course from a prior term?

You can access schedule of classes for previous terms online to search for courses offered in previous terms up to two years past.

Prerequisite Enforcement

This page provides a general overview of prerequisite enforcement.

The official prerequisite policy has further details.

  • Prerequisite — a course or courses or test score that must be satisfactorily completed before enrolling in another course.
  • Concurrent prerequisite — a prerequisite course that may be taken prior to or concurrently with the course requiring it.
  • Corequisite — a course that must be taken concurrently with another course.
  • All sections of the same course will carry the same prerequisites. Prerequisites should only be enforced where there is substantial evidence that a specific prerequisite course is essential for success in a given class. Departments should be selective and targeted in their decisions.
  • Enforced prerequisites may not be applied to X99 or blanket courses because these courses offer multiple topics. Section restrictions such as 'Departmental approval' may be used to control registration for these special courses.
  • Enforcing prerequisites for 100- or 200-level courses (with the exception of certain courses such as math or foreign language) should be greatly limited. Students will have real difficulty fulfilling bacc core requirements in a timely manner if many of these courses require the completion of course prerequisites. Also, students who are dually enrolled will be at a disadvantage because their partner school enrollments are not entered into their Banner records until after the beginning of the next term.
  • Departments are encouraged to review their decisions regarding OSU equivalents for transfer courses and make certain they are up to date and complete. Revisions and changes to transer equivalencies are coded into Banner by the Office of Admissions. Up-to-date transfer equivalencies help reduce the number of students seeking exceptions. Most students have transfer credits in their academic history.
  • Be prepared to handle exceptions and appeals from students in a rapid manner. Students register 24 hours a day, 7 days a week, and often must compete for available space in classes. A delay of 2 or 3 days could mean the student loses the window of opportunity to claim a seat in a class.
  • Expect slightly lower enrollments in courses with enforced prerequisites. Drops in enrollment may be temporary for the first few terms of enforcement or they may indicate permanent patterns. Some students will shy away from elective courses that have enforced prerequisites.
What prerequisites will be checked during registration?

Only those courses—selected by the departments—with a specific subject prefix and number, such as MTH 111, that have been completed with a passing grade of D– or better prior to enrollment or concurrent with the course being registered for. Some colleges have higher minimum passing grade requirements; for example, the College of Engineering requires a C. Minimum passing grades for prerequisite courses are displayed within brackets, e.g., MTH 111 [C–].

How does course prerequisite checking work during registration?

Banner checks the student's academic record, including transfer credit, to see if the prerequisite course has been successfully completed with a passing grade. If the course was not successfully completed, the student will be told the prerequisite has not been met and he or she will not be allowed to register for that course. Prerequisite checking will occur for all students who wish to take the course, regardless of level, rank, or college.

Banner also counts as "satisfied" any prerequisite that the student is currently enrolled in. However, if the student fails to satisfactorily complete the currently enrolled prerequisite course after registration, he or she will be disenrolled from the next term's course.

Course prerequisites Banner CAN enforce:
  • Specific courses with subject code and number that are satisfactorily completed, e.g., SOC 204 with a minimum grade of D–.
  • Transfer equivalents to OSU courses articulated by the Office of Admissions.
  • Standardized placement test scores that have been recorded in Banner.
Course prerequisites Banner CANNOT enforce:
  • Generic courses, such as a "social science course".
  • Courses not offered by OSU.
  • Transfer credit that has not been articulated to a specific OSU subject/number, such as LDT and UDT course numbers.
  • Older OSU courses (pre 1990) no longer contained in our Banner catalog.
  • Courses for which the student received a mark of N, W, I, F, U, AU, Y.
  • Undergraduate-level prereqs for graduate-level courses. The system does not search undergraduate transcripts of graduate students.
Will we still have prerequisites that are not enforced?

Yes, departments may continue to list prereqs that are not enforced during registration. Such prereqs may be enforced at the instructor's or department's discretion after registration. Both types of prereqs will be listed in the General Catalog and online Schedule of Classes (SOC) and labeled as "PREREQS:"

How do transfer credits satisfy prerequisites?

Transfer credits are brought into a student's OSU record when the Office of Admissions articulates those credits to OSU equivalents as directed by departments. Where there are no direct equivalents, the transfer credit will not count toward prerequisite compliance during registration without an override exception being granted by the department.

How will we handle exceptions and appeals?

Some students who do not meet prerequisites may wish to appeal to the offering department for an exception. Departments will be able to grant exceptions by entering overrides into Banner. Overrides will then allow the student to continue with their registration. If desired, override permissions may be entered into Banner in advance to the start of registration, with an override code of PREQ.

Priority Registration

What is priority registration?

Students are assigned registraton dates and times according to their student status and credits earned. The registration schedule is separated into two phases.

  • Phase I: Undergraduate students are eligible to enroll in a maximum of 16 credits and waitlisting is not available. You may enroll from your eligibility date until the end of Phase I. At the close of Phase I, registration is closed for a business day while the system is enabled for Phase II.
  • Phase II: You may waitlist courses that have waitlisting available and the maximum credits for undergraduates is raised to 19.
The priority registration schedule

The schedule displayed in the online catalog represents a range of dates and times during which students will be eligible to register depending on their status and credits earned. For detailed information about your registration dates and times, log into MyOSU, click on the Student tab, and under Registration Tools select "View Priority Registration Status.” Here you will see the specific dates and times assigned to you for Phase I and Phase II of registration. Your registration status and times will be available approximately one week before registration begins.

Phase 1 & II Priority Registration Calendars by Term in Online Catalog

When and how are PINS assigned?

The Office of the Registrar assigns registration PINS to students at the beginning of the current term for the next available registration term:

Flow chart for PIN assignment

PINs are assigned to students on the following timescale:

Week 3
(After add/drop deadlines)
From the beginning of week 3 onwards, PINs start being assigned to students automatically based on the term PIN rules set up for individual colleges.
Weeks 3–4

Some students are assigned PINs manually based on a particular status, e.g., disability access students, First-Year Experience students, student athletes, international Exchange students, etc.

This takes up to two weeks because information must be gathered from many departments. During this time, it is possible that a student’s PIN will be updated from one that was automatically assigned to one that reflects a particular status.
Week 4 At the end of week 4, the Office of the Registrar informs all advisors that PIN assignment processes have been completed.
Weeks 5–7 Advisors meet with students to distribute PINs and plan registration schedules.
Week 7 Priority registration phase 1 opens at the end of week 7.

Students can view their bill by logging into their MyOSU account and clicking on the Paying for College tab.

When is payment due?

E-bill statements are sent to ONID accounts on the 5th of the month. Balances not paid by the 1st of the following month are considered past due and interest begins to accrue.

Payment Options

Bills may be paid via e-check, personal check, money order, cash, or credit card.

Waitlisting Courses

If the course you want to enroll in is closed, see if it has an available waitlist. Courses can be waitlisted online during Phase II registration; refer to the priority registration calendar.

Watch a how-to video about how to waitlist courses

If you’ve never waitlisted a course before, watch the Waitlisting Video to get started.

If you know the CRN of the course: Login to MyOSU, click on the Student tab, and under Registration Tools choose Add/Drop classes, scroll to the bottom of the page, enter the CRN and click submit. The page will reload. Scroll to the bottom, use the action column to choose waitlist, and click submit again. Scroll to the bottom of the page and verify that you have been waitlisted for the course.

When waitlisted for linked courses such as lecture and laboratory or lecture and recitation, both CRNs, for lecture section and laboratory/recitation section must be present. If a laboratory/recitation section is waitlisted, from the dropdown menu for the waitlisted section of course select “Register” AND enter the CRN for the Lecture in the CRN box before you click “submit changes” to register. If you are waitlisted to the lecture, select “Register” from the dropdown menu AND enter CRN for the laboratory/recitation section in the CRN box before clicking “submit changes” to register for the linked course.

To waitlist a course using the Class Search feature: Login to MyOSU, click on the Student tab, and under Registration Tools choose Add/Drop classes, scroll to the bottom of the page, and click Class Search. Here you can define the criteria for the course you are looking for. Once the course is identified select it and click Add to Worksheet. The Add/Drop classes page will reload. Submit the request. Scroll to the bottom, use the action column to choose waitlist, and click submit again. Scroll to the bottom of the page and verify that you have been waitlisted for the course.

Waitlist Information

With the exception of Summer term, waitlisting will be available only in Phase II of the priority registration schedule.

Not all classes have waitlisting. Departments choose which sections will have a waitlist. The online schedule and course look up will display waitlist details for each section including the waitlist maximum and the remaining waitlist seats.

All registration restrictions (prerequisites, major/minor/option, etc.), with the exception of Duplicates, Links, and Time conflicts, are enforced at the time a student waitlists the course. However, any duplicates, links, and time conflicts must be resolved at the time the student enrolls in the waitlisted course.

Waitlisting remains active through Sunday midnight at the beginning of the second week of classes. Students may waitlist up to 3 courses.

Check out our WL FAQs for more information.

How does it work?

Once you are on the waitlist for a course, monitor your ONID email account frequently.

When an opening becomes available you will receive an email directing you to return to your registration and enroll in the course within the designated 24-hour window.

If you do not enroll in the course within 24 hours, you will be removed from the waitlist.

At the time you attempt to register for the course the system will check for registration errors including Time Conflicts, Duplicates, and Link Errors. If you have a registration error, you must resolve it and enroll within the 24 hours or you will be removed from the waitlist and the available seat will be passed on to the next student on the waitlist.
