About USACO Guide
USACO Guide is a free website that collects curated competitive programming tutorials and practice resources, organized from USACO Bronze through Platinum. It is created by the Competitive Programming Initiative and is written by USACO contestants, including two-time IOI winner Benjamin Qi. The guide lists topics that have historically appeared in USACO contests, and it includes practice problemsets and solutions across a range of difficulties.
The guide does not claim to be an official USACO syllabus, and it makes no guarantees about topics in future contests. Its content is structured around USACO, but the homepage states that people who do not take USACO can also use it.
