What it means


The enrollment in this course is restricted by class (Freshman, Sophomore, etc.). You may not enroll until you reach the appropriate standing.


The class has reached enrollment capacity. See Closed Course Registration for more information.


Co-requisite courses must be taken at the same time. You need to register for both courses at the same time. To do this, add the first class to your worksheet. Find the second class and add it to your worksheet. Now go back and “submit changes”. Double check your schedule to ensure you registered before logging out.  Another way is to enter both CRN numbers on the Add or Drop Courses menu.


Certain lectures, labs, and/or discussions are "linked" together. You must register for both the lecture, lab and/or discussion at the same time. To check for Linked requirements, click on the blue CRN number on the schedule and read the directions just below the title of the course. (e.g.; General Biology I - 10229 - BIO 120 – 10 Students registered in section 10 must also register for a lab (903-946).) 


Only students in certain majors are allowed to register for this course. If you have not yet declared your major, you should do so. If you are not within the major, you may ask for a permit. See the override request process for more information.


You are trying to take more hours than allowed (20 undergraduate credits). You must reduce the number of hours on your schedule or get permission. You must have the signature of your advisor on a completed registration form and then take the form to the Student Academic Success Center 200 STU for approval.


The enrollment in the course is restricted. Review the restriction criteria using the instructions above. If you qualify, contact the department for more information.


You do not have the pre-requisites for the course. You should adjust your academic plan to take the courses in the appropriate order. Seek advising if you need assistance with reviewing the requirements. If you will be taking the pre-requisite at another institution or through testing prior to taking this course, you may request a pre-requisite override. See the override request process for more information.


You are trying to take 2 courses that meet at the same time or have overlapping times.  Select different sections that do not overlap.
