Target Audience

This class is targeted to people who are familiar with Bronze concepts. It teaches you the major concepts needed for Silver. If you are already familiar with Silver concepts, this class will likely be too easy for you.

Additionally, this class is heavily video-based. If you learn better through text, you may want to use the USACO Guide instead.

Programming Language

Both C++ and Java have first-class support. Python is also supported, but we're still working on adding Python videos to some sections.

Pricing

These classes are not for profit -- instructors are unpaid and volunteer their time to help USACO contestants. That's why we've chosen to make these classes free, and open to everyone. If you want to support us, you can make a donation via PayPal instead.

How is this different from the Guide?

These classes follow the Guide curriculum, but are video-based rather than text-based. We also selected a subset of the most important Guide problems rather than using all of them.

How do I promote from Silver to Gold?

First, you should take this course so you know all the major Silver concepts. Then, you'll need to practice with old USACO problems (or USACO Guide problems). The goal of taking this course is to make you able to attempt Silver problems and understand editorials when you get stuck.

Important Information

1. If you already know all the Silver concepts, this class may be too easy for you.

2. The content of this course is extremely similar to the USACO Guide. The difference is that this course is video-based rather than text-based. If you're learning fine with the USACO Guide, there is no need to take this class.
