COS rooms are located in building D (entrance from POW street). Before visiting the COS it is necessary to collect a "Ticket". The ticket machine is located on the first floor opposite the entrance to the faculty. Ticketing starts 30 minutes before the office hours and ends 15 minutes before the end.

You can also book a visit on the website:

3 After selecting a particular field of study a calendar will appear.
4 Select the day and time of the visit. After selecting the time, the information about the ticket number will be displayed, which means that the booking has been successfully completed. If, after choosing a date, the time schedule does not appear, it means that there are no more tickets available for the chosen day, i.e. the limit of available reservations has been reached.

6. In the side menu under "Bookings" ticket can be canceled. To select the next ticket you need to log in again.

NOTE!
If you do not see the dates in the online booking, it means that the "online" tickets have already been exhausted. A separate pool of tickets is allocated at the stationary ticket machine, although it also has a limit.
