USACO Silver Comprehensive Training

This course deepens our students’ competitive programming and problem-solving knowledge and gives them the tools they need to succeed in the Silver level of the USA Computing Olympiad. Major focus topics include binary search, data structures (e.g., priority queues), recursion (especially on trees), and graph search algorithms. This material is not only important in competitive programming, but very useful in computer science and programming in general!

Who Should Take?

We expect USACO Silver students to have taken our USACO Bronze class, or to already be at the Silver level or close to advancing from the Bronze level (i.e., scoring 500+ in timed contests). If you have not yet competed in USACO, this course is only suitable if you have prior experience in competitive programming and algorithmic problem-solving and you feel comfortable solving USACO Bronze problems from recent years.

Students should also be comfortable coding in at least one of C++, Java, and Python. Although many Silver problems are fully solvable in Python, C++ provides a significant advantage starting at this level, and is all but required for success at the Gold level. Although our course does not include C++ lessons per se, it encourages the use and engagement of C++.

Many contest problems are quite mathematical, so students should have at least a prealgebra level of math experience. Algebra is recommended as a pre- or co-requisite.

The class was great. I enjoyed learning, and I was surprised to find I sat for so long doing math. It was lots of fun!
