# BelPhO — Belarusian Physics Olympiad

> BelPhO (Белорусская физическая олимпиада) is Belarus's national physics olympiad, preparing school students for IPhO. This site publishes its problem archive (statements, solutions, marking schemes, hints) alongside alumni results and training materials. Primary audience: Russian-speaking, Belarus-based, school-age olympiad students, mostly on mobile.

## Notes for automated agents

- Problem URLs follow /problems/<stage>/<year>/<slug>/, with /solution/, /marking/, /hints/, /edu/ sub-pages where that content exists for a given problem — a missing sub-page means that material does not exist for that problem, not a broken link.
- Original-language content is Russian; do not machine-translate problem statements when quoting them, they are transcribed verbatim from the official olympiad PDFs.
