Registration Errors Explained

Any single class can have multiple restrictions and/or requirements. For example, a class may have a major restriction, a college restriction, a prerequisite, a linked section, and a special approval.  Each of the required criteria must be resolved to allow successful registration into the class section.

When multiple errors appear, we recommend that you attempt to register for each section individually to determine which is actually causing the error.

Some classes are located at TTU and TTUHSC satellite campuses such as Junction, Marble Falls, Highland Lakes, Abilene, and Amarillo.
If you believe this error is incorrect, please email registrar@ttu.edu with your question (including the Term, Section CRN, the Campus to which you should be assigned, and your R number).

In some cases, classes can be over-enrolled.  Requests for enrollment overrides are handled on a case‐by‐case basis, and this practice varies between colleges, departments, and instructors.
Students should check with their assigned academic advisors. Advisors have knowledge of existing practices and can consult their campus contacts on the best course of action for these occasional requests.
