The **American Junior High School Mathematics Examination** (*AJHSME*) for students in grades 8 and below, begun in 1985, was the predecessor of the AMC 8, administered by the American Mathematics Competitions. Since 1999, the name has been changed into the **American Mathematics Contest 8** (*AMC 8*).

All problems from past AJHSME exams (1985-1998) and AMC 8 (1999–2016) form our “big data” system. We used data/text mining and predictive analytics to examine the types, styles, frequencies, and characteristics of questions in all these materials, and then completely “decoded” the AMC 8. For all questions on the recent AMC 8 contests, we can find their “ancestors” and “roots” from the old AMC problems. Therefore, __the best way to prepare for the AMC 8 is to practice by solving old AMC ____problems!__

We provided **14 sets of previous real AJHSME tests **(1985-1999) with answer keys and also developed **20 sets of AMC 8 mock test** with detailed solutions to help students prepare for the AMC 8 contest.
