1. Official AMC 12 from previous years with solutions: Use these tests with a 75 minute timer to simulate test taking situations. The AMC's are increasing in difficulty every year, so only AMC 12 contests from 2021 Fall and after are representative of the difficulty of recent AMC 12.
2. AoPS Created AMC 12 Mock Contest 2023: A high quality mock contest created by Art of Problem Solving problem writers
3. AoPS Created AMC 12 Mock Contest 2022: A high quality mock contest created by Art of Problem Solving problem writers
4. AoPS Created AMC 12 Mock Contest 2021: Another high quality mock created by Art of Problem Solving problem writers
5. AoPS User created AMC 12 Mock Contests: These mock contests are created by users on the AoPS forums and are of varying quality and difficulty levels. Still a good practice if you have completed all the previous year’s AMC 12 contests.
