About This Guide
Warning: This guide is NOT a syllabus!!
- For Bronze, Silver, and Gold contestants, we aim to be a "one stop shop," meaning that this is the only site you have to use to be exposed to most (if not all) of the topics required for Bronze to Gold.
- For Platinum contestants, we'll try our best to cover the main topics.
- The "Advanced" section contains material that is relevant for USACO Camp and beyond.
Note: We are currently focusing on the General - Gold sections. Modules that are part of Platinum and Advanced will remain mostly incomplete for the time being.
How to Use This Guide
- Use the Module Progress dropdowns (to the right of the module title and at the bottom of the page) to track your progress through this guide! Changes will be reflected by the navigation bar on the left.
- If you're stuck, ask for help in the USACO Forum, an unofficial Q&A forum for USACO contestants and competitive programmers.
- Read through all starred resources before continuing!
- We highly recommend doing all starred problems. If you need more practice, try some of the unstarred ones.
- Difficulty represents how challenging a problem is expected to be to someone after they read through the module, and is not comparable across modules.
- It's okay to skip "Very Hard" or "Insane" problems in Bronze - Gold and return to them later.
- See Introducing Modules for more information.
Skipping around is especially recommended for higher level contestants (Gold/Platinum). Feel free to mark a module as "Skipped" and come back to it at a later time!
For lower level contestants, the guide is generally designed to be completed in order. However, feel free to skip certain modules and come back to it later.
