The real AMC 8 gives you 40 minutes for 25 problems. Choose your working time below — start at 10 minutes for a sprint drill, or use the full 40 for an authentic run.
How this set works
Problems 1–8 are gentle warm-ups; 9–18 build in difficulty; 19–25 are genuine AMC 8-hard.
Every unit is mixed together, just like the real exam — arithmetic, algebra, geometry, number theory, and counting all appear in rotation.
When time runs out, the round ends automatically and your score appears.
After scoring, only the problems you got wrong are reviewed in full — with the correct answer and a short, exact explanation.
Scroll past your results for the Challenge Extension — ten very hard, easy-to-miss problems with instant feedback and confetti on correct answers.
Use the print button any time for an ink-light PDF booklet with the answer key on the last page.
