The AMC 8 is a middle school level math competition and the first stage in selecting students to represent the US in the International Math Olympiad. This course covers all of the exam questions from the past three years. The lessons are organized by topics: Arithmetic, Factors, Fractions, Algebra, Geometry, Probability, Graphs, and Combinations in that order. Some topics require more than one lesson because there are many questions in it. It is suitable for students in grades 5-8 who are preparing to participate in AMC8.
