Who Should Take This Test

MATHCOUNTS is the largest tournament-style middle school math competition in the United States. It features a series of levels that starts from competitions within each school to determine the school's official representatives, followed by competitions at Chapter (local region), State, and National levels. This exciting journey brings math enthusiasts together to meet mathematical peers with similar experience. Due to the reach and prestige of this competition, its many levels of competition, and its ability to bring students to meet face-to-face, MATHCOUNTS is the focus of many middle school students' math contest careers.

If you're looking for a MATHCOUNTS mock test to try out, this is the place for you! Our electronic test will also report your strengths and weaknesses by topic.
