Announcements

• Those students who want to use DM18 as their bachelor project must sign a statement confirming this. It is not possible later to decide to use DM18 as the bachelor project if one did not sign up for this at the beginning of the course. The engineering study board has decided that datatechnology students are not allowed to use DM18 as a bachelor project. The procedure for computer science students is the following: no later than February 9 at 12:00, you must have sent an e-mail to the lecturer with your full name, e-mail address (the one you read daily), IMADA login, and first 6 digits of your CPR number. Please use "DM18: bachelor project" as the subject of the mail. The secretaries' office will then prepare statements and you will be informed as to when you can come by and sign.
