Online USACO Practice Exams

These courses are composed of four USACO Practice Exams which is very similar to one season in USACO. Thus, the last exam may be harder as in the last USACO contest, US Open.

The tests are prepared by AlphaStar Academy. They are similar in style to the official tests. The difficulty is intended to be  a little harder than the recent official ones since the official exams get more difficult over the years. The goal is to give a chance to the students to improve their exam strategies with brand new problems, not using any problems from past competitions.

The solutions will be demonstrated by the instructor during the live sessions. The recordings of the live sessions will be provided to both live and self-study course students. Students are expected to take the exams online beforehand.

The following services will be provided:
