Add and Drop Deadlines
The "last date to enrol without permission of course instructor" deadline represents the last date students have unrestricted access to the registration and enrolment system. After that date, you must contact the professor/department offering the course to arrange permission.
You can drop courses using the registration and enrolment system up until the drop deadline. After that, you will receive a grade for the course.
