What is the difference between registering for a course and signing up for labs?

Registering for a course is a formal procedure that gives you the right to participate. It requires checking if there are available places and if you have the necessary prerequisites. Signing up for labs in Webreg is a more informal way of dividing students into lab groups and keeping track of which students are active in the course. Normally, you have to register for a course before you can sign up for labs. If you have questions regarding registration, please check in Lisam or contact Info Centre.

Why can't I log in?

You need an active student LiU-ID to login. If you recently activated your account, or have registered for an IDA course for the first time, wait until the next day for the system to catch up.

Why can't I see my courses when I log in?

You can only see the courses for which you are registered. If you register for a course, it will show up in Webreg the next workday. Please note that late registrations might be further delayed by the admissions office. Always make sure you register in time.

Why can't I sign up?

For some courses, Webreg might require you to register for the course before you can sign up. Also, the sign up deadline might have passed. If you have problems signing up for labs, please contact one of the assistants in the course, or the examiner.
