Communication Error: This is basically a system busy signal. The best advice is to try again later. If the problem persists, contact the Registrar’s Office.
Link Error: This is usually caused by an incompatibility between lecture section and lab section choices (you might have registered in a SOC 2290 lecture section without also registering for a SOC 2290 lab section, for example).
Repeat Count Exceeds Zero: This occurs when you are trying to register for a course that you have taken previously. You will need to speak with a Faculty of Arts student advisor, to ensure you understand the rules for repeating courses, before you will be allowed to register.
College Restriction: This occurs when you try to register for a course that is restricted to a certain group of students during part of the registration period. It usually means that you won’t be allowed to register for the course until after a certain date (often mid-August).
Program Restriction: This occurs when you are trying to register for a course that is restricted to students in a particular program or faculty.
Duplicate CRN: This usually means that you are trying to register for the same course twice.
Maximum Hours Exceeded: This means that you are trying to register for more than the maximum of 15 credit hours in a term. If you didn’t intend to do that, check to sure you have selected the proper course sections/terms. To get permission to take more than the maximum credit hours in a term, you need to speak to a Faculty of Arts student advisor.
Preq and Test Score Error: This usually means that you have not completed the prerequisite to the course for which you are trying to register. Note that you don’t necessarily need to have completed the prerequisite course before registering for a subsequent course. For example: SOC 2510 (with a grade of C or better) is the prerequisite for all subsequent Criminology courses. If you are registered for SOC 2510 in the Fall term, you will be allowed to register for higher-level Criminology courses offered in the Winter term (even though you haven’t actually completed SOC 2510 yet). Note that if you fail to successfully complete SOC 2510, you will be required to withdraw from any courses for which SOC 2510 is the prerequisite.
