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.

In order to ensure student success, we host office hours every Tuesday and Thursday at 5:00-6:00pm PT where students can ask for help from instructors.

Course Info

Class Format

A CPI course consists of 9 weekly classes, each of which lasts 2 hours. Classes will go over challenging example problems and contain problemsets for homework.

All classes will be recorded, so don't worry if you are unable to attend every 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. There will be weekly office hours for students to get help from instructors.

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