Common Errors with Adding Classes

This article covers some common errors with adding classes and what they mean.

Common error 1: Class is Full

Class is full

This error means that the class has no open seats and you did not choose to add yourself to the waitlist (if available). Click Return to Class Preferences to check if a waitlist is available and add yourself to the waitlist.


common error 2: Requisites have not been met: Pre-requisites


This error means that the pre-requisites for the class have not been met. A list of all the pre-requisites will be shown.

In the above example, PSYC 201, PSYC 202, and PSYC 300 must be complete (or in progress during the current semester when enrolling for the next semester) before enrolling in PSYC 465.


Common error 3: Requisites have not been met: Co-requisites


If you try to enroll in co-requisite classes one at a time, you will get an error. However, if you add the co-requisite classes to your shopping cart and then enroll, the enrollment for both classes should be successful.

This error means that co-requisites for the class have not been met. Co-requisites are classes you must take at the same time (e.g., a laboratory class that you take at the same time as the main class).

In the above example, to enroll in EGEE 483, you must also enroll in either EGEE 409 OR EGCP 371.


Common error 4: Department Consent Required

Department Consent Required

"Department Consent Required" means that the department needs to grant you permission to enroll in the class. Contact the department for more information on how to receive permission.

In the above example, it is a Psychology course, so you would contact the department of Psychology for assistance.


common erro 5: Hold (Negative Service Indicator)

Some holds (also known as negative service indicators) that are placed on your account prevent you from adding (or dropping) classes. You will need to view the hold details to find out what you need to do to clear the hold. When the hold is cleared, you will be able to enroll.


common error 6: Time Conflict with other enrolled classes

Time Conflict with other enrolled classes

If the scheduled time of a class conflicts with another class (or classes) that you have already enrolled in, you will not be able to enroll. For example, if you are enrolled in a class that meets Tuesdays and Thursdays from 8:30am - 9:45am, you will not be able to enroll in another class that meets on Tuesdays and Thursdays from 8:30am - 9:45am.


common error 7: Exceeded Maximum Unit Limit

Exceeded Maximum Unit Limit

There are limits as to how many units that you can take each semester. If enrolling in a class will cause you to exceed your unit limit, you will not be able to enroll in the class.

If you want to drop one of your classes to enroll in the class, consider using the  Swap Classes Opens in new window  feature to drop the class only if you can add the new class.


common error 8: Repeat Related Issues

If you have already taken this class and passed it, you may not be allowed to enroll in the class again.


common error 9: Instructor Consent Required/Enrollment Deadline has passed

Instructor Consent Required

The Instructor Consent Required message indicates that the deadline has passed to use Titan Online to enroll. You will need to use the Late Add (Petition for Late Addition of Class) form located on the Registration and Records Forms webpageOpens in new window to enroll in a class.
