Instruction for Teachers: Every teacher when setting the course has to assign a course specific  "Enrollment Key" while setting the enrollment method as self-enrollment. This "Enrollment Key" has to be informed to the students via email or phone.

Instruction for Students: When you click on the course the system will ask for the "Enrollment Key" which has been circulated to you by the course coordinator/ teacher. If you did not get it inquire from friends or the teacher.
