The confirmation of thesis registration is requested by different authorities, such as the revenue office or the scholarship office.
Until now, you had to go to the Examinations Office to get the confirmation. You were given a photocopy of the original application form, stamped by the Office.
From now on, you can dowload an official confirmation of thesis registration via LFU: online.
Under LFU:online > My papers there is an overview of all your theses. You can retrieve the confirmation of thesis registration as a PDF document for each thesis you are currently working on (status: in progress).
