Terms
Use freely, attribute properly.
OlympiadHQ is offered as a public-good archive at no cost. The terms below explain what you can do with the material on the site and the limits of our role.
The problems
Each problem displayed on this site carries the licence and attribution of its source dataset. The current sources are:
- MathNet, Alshammari et al. (ICLR 2026, MIT CSAIL), released under the CC BY 4.0 licence.
- MATH, Hendrycks et al. (NeurIPS 2021), released under the MIT licence.
- HARP, the Hard AMC/AIME Problems dataset, released under CC BY-SA 4.0.
- Selected national competition papers (CEMC, etc.) reproduced under their stated educational-use terms.
You may reuse any problem under its own licence. The attribution and licence label visible on each problem page is the authoritative reference.
The site itself
The typesetting, layout, and code of olympiadhq.com are the work of Vamshi Jandhyala and made available without warranty. The site is offered as-is. We make no guarantees about correctness, availability, or fitness for any particular use.
Takedown
If you are a rights holder for any problem reproduced here and would prefer it removed, email vamshi.jandhyala@gmail.com and it will be removed.
Acceptable use
The archive is here for human readers and reasonable scripted access. Bulk scraping that damages availability for everyone else is rate-limited at the edge and may be blocked. If you would like a clean copy of an upstream dataset, fetch it from the dataset author rather than from this site. The upstream copies are canonical and will be more useful for your work.
Governing law
These terms, and any matter arising from them, are governed by the law of England and Wales.
