I have sent an email to the courses email address (the ditributor). In that email were the time sliot for every candidate (I don't repeat the names here).
Everyone should therefore know his or her slot. I cannot check if the email list is up-to date (I have no access to that and cannot see who is on it). The list contains the oficial UIO/IFI email addresses, not possible gmail-accounts or similar, so one has to look there. In case someone does not know the slot, you have to show up 8:45 in the morning (or contact me today).
