First Round 2025/2026

For the first time, we have our first round of the Swiss Olympiad in Informatics as a multiple choice round on OlyPortal. The test takes 40 min and is ideal to be taken in class as a fun classroom activity. The test is open from September 1st until September 26th. Afterwards, we will contact the best participants, who qualify for our workshops and the second round.

The test does not require any preparation. The test comprises of general algothmic and logical questions, and some pseudo code questions.
