→ About Contest
The CTU Open Contest is a preparation for the CERC. It is a local contest held at CTU Prague and its main goal is to choose the team representing CTU in Central European Regional Contest. To make the competition more interesting, the Contest is open for any Czech university. The universities from the Czech Republic are not required to participate in CTU Open Contest. But it is strongly recommended, because the participants of CTU Open will be preferred in CERC if there are too many teams applied. Besides, it is a very good preparation. The Contest Rules for CTU Open Contest are the same as CERC Rules. The only exception is that the contest language is Czech.
