Common Errors with Adding Classes

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

Class is Full

error indicating 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.

Requisites have not been met: Pre-requisites

error indicating pre-requisites have not been met

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.

Requisites have not been met: Co-requisites

error indicating co-requisite has not been met

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.

error indicating 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.

Hold (Negative Service Indicator)

error indicating hold on student's account

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. View instructions on how to view holds on your account.

Time Conflict with other enrolled classes

error indicating time conflict

If a 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.

Exceeded Maximum Unit Limit

error indicating maximum units exceeded

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. This also applies to being added to the wait list for a class: you cannot be wait listed for more units than you can enroll in.

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

repeat related issue

If you have already taken this class, you may not be allowed to enroll in the class again, depending on your previous grade in the class and how many times you have repeated it.

If the deadline has passed to use Titan Online to enroll in a class, you will need to use the Late Add (Petition for Late Addition of Class) form located on the Registration and Records Forms webpage to enroll in any classes.

Elizabeth Schuster

I have met the requisites, but it still says that I have not met the requisites.

Camille Johnson

Hi Elizabeth! You may want to double check your TDA to make sure that it reflects the prerequisites for the class you're trying to add. For transfer classes especially, sometimes adjustments need to be made to make sure they audit properly.

If you have met the requirements for the class but get a "not met" error, you can contact the department offering the class and see if they can issue you a permit to register for the course. When contacting the department, provide your CWID, proof of meeting the requisite, and the section of the course that you're trying to add.

Jacob Ryan

I followed the instructions for adding a corequisite class but it will not allow me to enroll. I need to take a lab with my psyc class but it will not let me.

Lori Arthur

Hi Jacob! Unfortunately, you will need to contact the Registration & Records Office to determine why you are not able to enroll in both courses as it may be related to the specific courses or perhaps your specific enrollment limits (e.g., perhaps enrolling in both classes will put you over the maximum number of units you can take?). Contact them at [email protected] or 657-278-7601. Or visit the Registration & Records Office in LH-114.
