Who We Are

AMCUA is a volunteer organization that provides American Mathematics Competitions (AMC) prep classes and offers AMC contests to students currently residing in Ukraine. This organization was started by Larisa Bukalov in response to the Russian invasion of Ukraine. Our goal is to deliver additional academic as well as social and emotional support to Ukrainian students that are interested in mathematics.

We are always looking for math enthusiasts and supporters that would like to volunteer. If interested, have a working knowledge of Ukrainian or Russian language, and trained as a math professional please do not hesitate to contact us and join our team.
