Unable to Add a Class in MyDelta

There are a few reasons you may not be allowed you to add a class to your schedule in MyDelta:

Time Conflict

Time conflicts occur when two classes are scheduled at overlapping times. MyDelta does not allow you to have time conflicts, such as enrolling in two classes that both meet on Mondays at 10 a.m.

Prerequisites are requirements for taking a class, such as completing a prior course. You will not be allowed to enroll or waitlist for a course, if you have not met the prerequisites.
If you encountered an error message regarding prerequisites, but believe that you have, in fact, met the requirements, we encourage you to try again. We have resolved most of the prerequisite issues that previously prevented enrollment
Invalid units taken error message: If you encounter an error message about invalid units taken, simply log out and try again. This should resolve the error.

A corequisite means a course you must take at the same time as another course or requirement. At Delta, if you are signing up for certain English and math classes, you may need to take a one-unit support class at the same time
If you are registering for a course with a corequisite, make sure both courses are in your shopping cart so you can enroll in them at the same time.
