IOI 2025

IOI 2025 is a benchmark for hard reasoning in science, technology, engineering and math. The official description says: "IOI 2025 - International Olympiad in Informatics 2025 competitive programming score". Below we describe in simple words what benchmarks of this type generally examine.

IOI 2025 measures hard reasoning in science, technology, engineering and math. In detail, it checks:

• graduate- and expert-level questions in science and math
• multi-step derivations where each step must be correct
• problems written to defeat memorisation (novel or recent exam problems)
• correct use of formulas, units and logical inference

The score is competition points on the organiser's official scale (e.g. a 42-point olympiad-style test). More points is better.
