When you submit your preliminary registration, your course selection(s) will be verified against a variety of registration criteria. If your course selection(s) does not pass the validations, you will be notified by one or more 'yellow' or 'red' lights. Each is accompanied by a message explaining the issue and provides instructions for resolving the issue.

Three of the most common issues are...

Time Conflicts between two of your selected courses. If you have two courses on your schedule that are scheduled to meet on the same days and time, or overlap, you will be notified by a 'red' light. You will need to drop or remove one of the courses and resubmit your preliminary registration to resolve this conflict.

Prerequisite(s) Not Met means that you have not fulfilled the prerequisite requirements needed to take this course. A link is provided for you to see the prerequisites for this course. You will need to remove this course from your preliminary registration and re-submit your preliminary registration.

Course Not Applied to Checksheet appears for a course that does not fit any open 'slot' on your checksheet. It may not satisfy your degree requirements. You may still take this course if there are no other issues by 'submitting with warnings.'
