Explanations of Awards

  • AIME floor: Before 2020, approximately the top 2.5% of scorers on the AMC 10 and the top 5% of scorers on the AMC 12 were invited to participate in AIME. Since 2020, the AIME floor has been set to a higher percentage of scores, likely to ensure that a consistent number of students qualify for AIME each year, rather than a fixed percentage. Usually, 6000-7000 competitors from the AMC 10 and 12 qualify for the AIME.
  • Distinction: First awarded in 2020. Awarded to top 5% of scorers on each AMC 10 and 12 respectively.
  • Distinguished Honor Roll: Awarded to top 1% of scorers on each AMC 10 and 12 respectively.
  • Honor Roll: Stopped in 2020. Previously awarded to the top 8% of the scorers on the AMC 10.

Stop spreading false information. Spreading unofficial AMC cutoffs and false information will result in a ban from editing powers in the AoPS wiki. (Is there a specific date available for December?)

Schedule Change

In April 2021, MAA announced they would be moving the AMC 10/12 to November, before the new year, and AMC 8 to January, after the new year; however, the AIME would remain after the new year. Thus there are two "2021 AMC 10/12s", no "2021 AMC 8", and one “2021 AIME”. All future AMC contests will follow this schedule.
