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.

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!
