Question Session: (Spørgetime)

Tuesday June 10, 2003, 13:15 - 15:00 Room 1.90.

Timetables of examn:

Detailed time schedule will be available no later than Tuesday June 10, 2003.

Each student will be examined for 20 minutes (evaluation included). Not long after the cancellation deadline (which is June 7, 2003), that is, 10 days before the examn you will find the scheduled time slot for all studens on this page. (If you do not appear on the list, then contact Kåre immediately.) I expect you to be ready 1 hour before the scheduled time, although the first three in the morning only need to show up 15 minutes before the first examn. Besides, the first three students in the afternoon after lunch break only need to show up 15 minutes before examn is started again. Oral examns may last a little longer than expected, so be prepared for a little waiting time. There are, however, always a couple who do not show up, so please be prepared to accept an earlier time slot if being asked on the spot! (Indeed, this is why I ask you to show up an hour early). If you do not show up or are not able to reach the IT-C or get ill, then contact Kåre immediately - you are welcome to call mobile 2246 7446 - 24 hours a day - leave a clear message, if I do not answer your call. [But please note: You also need to call the study administration and inform them about matters].

BEFORE June 10: In case you have special wishes regarding when you would like to take the examn, then send e-mail to Kåre about this, e.g. not early in the morning, or preferably the first day of examn. You are welcome to do this until June 10 2003. If possible I will try to follow your wishes - at prevoius examns all such requests have more or less been fullfilled. Equip your mail with subject: "EKSAMENSDATO". I will respond to your request - if you do not get a response within a few days after your first transmission, then retransmit. Please remember to state your NAME and social security number (CPR) in your request.

AFTER June 10:Below you will find the schedule a week before the examn (June 10, 2003). If you have received a time slot which does not fit well with your own schedule, then you MAY try to change with someone else - but you need to find someone to change with yourself! All interchanges must be mentioned to Kåre, in a written form before the first of the two involved time slots.

PLEASE REMEMBER Question Session June 10, 2003 kl. 13:15-15:00 - room 1.90.
