USACO Bronze


Class Description:

This class provides online training for the USA Computing Olympiad (USACO) Bronze Division, a programming competition looked at by colleges and used as a qualifier for the International Olympiad in Informatics (IOI). Classes will be held through a computer with a teacher online via live video conference, and during each lesson students will work on challenging sample problems with the help of a teacher. Then, students attempt a problem set for homework on the same topic covered in class, and are able to ask a TA for help during office hours.
The goal of this course is to prepare students to score well on USACO's Bronze Divison and help them advance to the Silver Division. Even though this class covers algorithms similar to CS02, this class is geared more toward USACO-style exercises rather than the AP style content of CS02. This class covers introductory problems, using simple algorithms. Topics covered include advanced uses of arrays, 2D arrays, strings, objects, etc. An example problem might have the student find the cow closest to a given point given a list of cows and their coordinates.

Class Package

Virtual Machine (VM)
A Virtual Machine is a remote desktop that allows students to connect to it from anywhere. We provide VMs so that students use it during classes and to work on homework.
Office Hours with Teacher's Assistants
Office hours are led by our highly qualified teaching assistants. It is an easy and free way to get immediate feeback on your code. Our homework is difficult - office hours can help you overcome obstacles and develop a stronger understanding of the material!
Audio Lectures
We provide pre-recorded Audio Lectures to allow for students to self-study, practice, and learn CS.
Student Progress Report
The parent account dashboard allows for parents to track their student's progress in the class.
