The Russian Federation has organized the Open Doors International Olympiad for the fourth time. This year introduces a doctoral track (analogous to Ph.D.) in addition to the usual master’s track. Depending on the chosen direction, the winners of the Olympiad will be able to enroll for free in the master's or postgraduate programs of their chosen University. Participants of the doctoral track will be able to choose a future research supervisor and pass an interview with them during the Olympiad.
