MathNet

MathNet is a large-scale research dataset and benchmark of olympiad-level math problems, released by MIT.

Although it was built to evaluate how well AI models can reason through competition mathematics, the dataset is publicly released, which makes it one of the largest free collections of high-quality olympiad problems.

What is in the Dataset

30,676 expert-authored problems with solutions
Spans 47 countries and 17 languages
Covers two decades of competitions
Includes problems from diverse domains

Why MathNet is Useful for Competitors

The scale and diversity of MathNet makes it useful as a problem source. MathNet consolidates problems from 47 national competition traditions into one place, many of which are hard to find elsewhere.

The included solutions also make it a strong self-study resource.
