Final grades



There are available rooms at the university students dormitory, block 55, in the Students town. The dormitory  is located 10-15  minutes away by bus from the university FMI, SU and the institute IMI BAN.

Transportation from the airport

The public transportation in Sofia is available from 05.00 a.m. to 11.00 p.m, all year round. The price of a ticket is BGN 1.00 (around EUR 0.50). Alternatively, you can buy a combined ticked for ten trips that costs BGN 8 (around EUR 4); please notice that this combined ticked may be used by only one person and you are expected to keep the last part of it with yourself. If you are carrying luggage larger than 60×60x40 cm, you are expected to buy a separate ticket for it. The ticket for a piece of luggage is the same as the ticked for one travel of a person. Use a perforator device inside the vehicle to mark your ticket(s).

For more information go to the web site of Sofia Public Transport Company.

The following is information how to reach your hotel or the Faculty of Mathematics and Informatics.

By plane
There are two passenger terminals at Sofia Airport. The regular No 84 bus line covers the route Terminal 1 – Sofia University Rectorate (Main building)  and it covers the route Terminal 2 – Sofia University Rectorate (Main building). When you reach the main building you have to take bus No 94, which will take you to Campus Lozenetz, where the Faculty of Mathematics and Informatics is located. The name of the bus stop is "Seminariata" and the building of the Faculty of Chemistry is visible from the bus stop. Please, remember to buy a ticket for your luggage as well. 

Or if you like to go to the dormitory bl 55 wh A at the Student town you could take bus 280 or 94 (a little bit longer ride) till the bus stop "Zimen dworec" (Winter castle- a big zaal for sports and concerts)  and then  follow the map.

By bus or train

You can take the buses 213 or 214 till "Orlow most" (Eagle bridge) and there you can change the bus - take 280 till the dormitory or 94 till the Faculty of Mathematics and Informatics.

Taxi service in Sofia
If you wish to order a taxi, you can turn to the office of OK Supertrans, located in the public zone of the Arrival Hall. The Company is at your service to transport you and your luggage to the desired destination. The average price of a trip from Sofia Airport to the city centre is BGN 12 (EUR 6). You can direct your complaints or opinion to the following telephone number: + 359 2 973 37 70. Ordering your taxi cab through the office of “OK Supertrans” will provide a safe trip for you. Alternatively, to order a taxi you can dial + 359 2 973 2121.

Transportation between Block 55 (in the Students town) and FMI, SU or IMI, BAN (where the lectures will take place)

The first and the third module of the course will take place at Institute of Mathematics and Informatics of Bulgarian Academy of Science (IMI, BAN),  Acad. Georgi Bonchev Str., Block 8, and the second module will be at Faculty of Mathematics and Informatics of Sofia University (FMI,SU), 5 James Bourchier blvd, Lozenec, 1164 Sofia.

You can use bus 94 to go to FMI, SU. The ride takes 17 minutes.

You can take the bus 280 to go to IMI, BAN.
