Mathleague.org
From AoPSWiki
Formerly known as the Great Plains Math League (GPML), mathleague.org runs the state high school math championships in Missouri (since 1998), Iowa (since 1999), Kansas (since 2000), and Arizona (since 2007). mathleague.org's test format can best be described as a hybrid between the MATHCOUNTS and ARML formats. mathleague.org also organizes ARML teams from several states.
