Posted by On February 7th, 2023, select middle school and high school students participated in this year’s AIME I Competition.
The problems can now be discussed! See below for the answer key for the 2023 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.
