By me you can get signed certificates of registration and results. If you want to drop a course or re-register for a course you should report this to me.
I have no special opening hours. The main reception, in the atrium on the first floor, you can get help with general questions, study certificates, purchasing compendia, retrieving written exams etc. Opening hours during semester: Monday-Thursday 8.45-16.30, Friday: 8.45-15.30.
I handle the LU-identity (LUCAT), assist booking in TimeEdit and update the departmental homepage.
