Rocket City Math League (RCML) is a free, student-run mathematics competition in the United States. Run by students at Virgil I. Grissom High School in Huntsville, Alabama. RCML was started in 2001 and has been annually sponsored by the Mu Alpha Theta Math Honor Society. The competition consists of a team round (known as Interschool) in the fall and 3 individual rounds in the spring.
The individual rounds are divided into 5 divisions: Explorer (Pre-Algebra), Mercury (Algebra I), Gemini (Geometry), Apollo (Algebra II), and Discovery (comprehensive). A student can only compete in one division that corresponds to the math course they are currently enrolled in or a higher level math course. Students may not compete in a level that corresponds to a math course they have already completed.
In the Interschool Round, all students from a school work on the same test and will submit a single answer sheet for the entire team. Interschool is divided into Junior Interschool and Senior Interschool. Schools can only compete in one Interschool level (Junior or Senior) determined by the competing student in the highest grade. Junior Interschool is made up of schools that have only 9th graders or lower competing in RCML. Senior Interschool is made up of schools that have any student that is in 10 grade or above competing in RCML.
