ScienceArena - EuPhO 2025: leaderboard

The European Physics Olympiad 2025 theory exam in ScienceArena (Zhao et al., 2026), solved one subpart at a time from text renderings of the questions. Points out of 30, awarded by an LLM judge applying the official process-credit rubric, calibrated against medalist grading; higher is better.

Metric: Score (out of 30): points awarded on the European Physics Olympiad 2025 theory problems, text-only question renderings; interleaved solving, one subpart at a time with earlier turns in context; open-ended physics and chemistry turns graded against the official solution and process-credit rubric by the authors' medalist-calibrated LLM-judge pipeline.
