The AMC (American Math Competition) is a series of tests which lead to the selection of the U.S. Math Olympiad Team which competes in the International Math Olympiad.  Along with MathCounts, the AMC series of competitions is the premier math contest for middle school students.

The AMC 8 is for students in grade 8 and below.  It is held in November.  Students are allowed 40 minutes to complete the 25-question multiple-choice exam.  Middle-school students who score well on the AMC 8 often take the AMC 10 in February.  A high score on the AMC 10 or 12 qualifies a student to take the AIME, which leads to the USAMO and eventually the MOSP and the IMO.  More information can be found at the AMC website.
