UT Arlington has enabled Validation Appointments. This feature allows you to plan ahead of your Enrollment Appointment. Using course validation, you will know in advance if you are eligible to enroll in the classes you have selected. It will check for things such as missing prerequisite requirements, holds, time conflicts, etc. This feature is called the "Shopping Cart Appointment"
Validating your shopping cart does not enroll you in classes. Once your enrollment appointment is open, you will need to register for your classes. Validation only shows you whether you meet the requirements to enroll in the classes selected.
