Registration for the competition is now open.

Science-Smart School of Sofia will be holding the fourth edition of our unconventional math competition - Izzi Math Challenge. The competition is organised in partnership with "Olimpmath" EOOD (rep. of The Union of Bulgarian Mathematicians).

Izzi Math Challenge is opened to students from 1st to 11th grade and aimed at applying mathematical knowledge by promoting analytical thinking and using a resourceful approach to problem solving. One of the challenges involved a three-dimensional math problem.

The competition will take place on February 20, 2027 from 11:00 to 12:30 at SMART Science High School (Sofia Tech Park: 111, "Tsarigradsko Shose" Blvd.). The duration of the competition for first grade is one hour (up to 12:00).
