Range AMC 8 covers from a middle school mathematics curriculum. Possible topics include but are not limited to: counting and probability, estimation, proportional reasoning, elementary geometry including the Pythagorean Theorem, spatial visualization, everyday applications, and reading and interpreting graphs and tables. Some of the later questions may involve linear or quadratic functions and equations, coordinate geometry, and other topics traditionally covered in a beginning algebra course. Usually covers mathematics syllabus in Grade 9 and Grade 10, including elementary algebra, basic geometry (Pythagorean theorem, area and volume formulas, etc.), elementary number theory and probability. Trigonometry, advanced algebra and advanced geometry will not be included. AMC12 covers all mathematics knowledge learned in high school, including trigonometry, advanced algebra, advanced algebra and part of calculus. Students who get great results in AMC 10/12 will be invited to participate in AIME. More difficult than AMC 10/12.
