Premium Quality, Affordable Cost.

Affordable doesn't mean low-quality.

With a team of past USACO Finalists, we've created classes of the highest possible caliber that are just as competitive as more expensive alternatives.

While our instructors freely volunteer their time to help teach these classes, we ask that students donate $100 to help fund the infrastructure costs of creating these classes ($4.16/hr). Of course, if you're unable to pay, you'll get access to these classes for free.

Want to try out the class before donating? The first class is free -- you can choose whether to donate after attending the first class!

Course Info

Class Format

A CPI course consists of 12 weekly classes, each of which lasts 2 hours. Classes will go over challenging example problems and contain problemsets for homework.

Instructors will be able to answer any questions students may have during class. Students will have access to an exclusive Q&A forum to get help from instructors after class.

Classes follow a flipped learning model to maximize the amount of time students have to ask instructors questions. Our curriculum is modeled off the USACO Guide.

Seats are limited. First come first served, so make sure to sign up soon!

Pricing

These classes are not for profit -- instructors are unpaid and volunteer their time to help USACO contestants. We recommend a $100 donation ($4.16/hour) to help support the creation of these classes and the infrastructure for the resources we provide such as the USACO Guide.

Financial aid is available. If you are unable to pay the full amount, just let us know!
