When setting up, keep in mind that drops before classes start are not drops. Registration eligibility rules are setup on this screen. Holds have to be written into rules to be effective. Colleague doesn't see a pre-requisite has been satisfied until a course is graded.
Colleague does tell operator that pre-requisite is underway.
Colleague does not look back to see whether a co-req has been taken previously. If it is not, the next person to attempt to register for a waitlisted course will be allowed to enroll in the class. Waitlist does not automatically enroll a student in a waitlisted course. Jeanne has notes on this. This is a direct tie in to the CRES screen Petition Required.
