 # 2022 AIME I Answer Key Released Posted by

Yesterday, select middle school and high school students participated in this year’s AIME I Competition (including some students proctored by Areteem online).

The problems can now be discussed! See below for the answer key for the 2022 AIME I questions as well as the concepts tested on each problem. All answers for the AIME are in the form of 3-digit integers.
