Registration Restrictions and Error Descriptions
Submitting your Course Reference Numbers (CRN) to register for classes will create a schedule and any registration restrictions or error messages.
The status column identifies the type of registration restrictions for each CRN. You can resolve some errors yourself (i.e., select an open section of a course), but others will require that you see your academic advisor.
Specific registration restrictions include:
Closed Section
A closed section status supercedes all other errors, meaning any other registration error may be hidden behind it. This status indicates that the section is full to its maximum seating.
Permission Required
The following status messages indicate that permission is required from a department or person in order to register for that section of the course.
Level Restriction
A level restriction status indicates that only students of a certain level (either undergraduate or graduate) can register for the course or that particular section of the course.
College Restriction
A college restriction status indicates that only students of a certain college or school can register for the course or that particular section of the course.
Major Restriction
A major restriction status indicates that only students with a certain major can register for the course or that particular section of the course.
Class Restriction
A class restriction status indicates that only students of a certain class (such as junior or senior) can register for the course or that particular section of the course.
Time Conflict
A time conflict occurs when the course displaying this status message is offered at a time that conflicts or overlaps with a course for which you have already registered.
Co-requisite
A co-requisite status occurs when another course must be taken during the same term as the course displaying the error. Register for the course indicated to correct this problem.
Prerequisite and Test Score
A prerequisite and test score error for a course or section indicates that a specific course or courses must be completed prior to registering for the course displaying the error.
Link Error
A link error occurs when a course has multiple parts (i.e., lecture, lab, and/or recitation) that must be taken in conjunction with one another. Although these parts have unique CRNs, they are one complete course when taken together. Only one part of the course, the lecture if applicable, will be associated with a grade and credits. The lab and/or recitation that must be taken with it will have zero credits and will not receive a unique grade.
- Lectures have sections like A, B, C, etc. and link identifiers of L1, L2, L3, etc. depending on how many lectures with unique times are being offered. Each number in the series (L1, L2, L3, etc.) has a specific set of lab and/or recitation sections that can be taken with it.
- Lab series have section numbers like 061, 061, 063, etc. and have link identifiers of Z1, Z2, Z3, etc.
- Recitation series have section numbers like 001, 002, 003, etc. and have link identifiers of R1, R2, R3, etc.
To correct a link error, register for courses with common link identifiers (i.e., L1, Z1, R1 or L3, Z3, R3).
