The Ultimate Guide to Qualifying for the AIME

Qualifying for the American Invitational Mathematics Examination is a process: build reliable fundamentals, learn to recognize contest structures, and use every mock to find the next skill to improve.

Start with the current qualification rules

For the 2026–27 contest cycle, MAA announced qualification scores of 100 or higher on AMC 10 and 85 or higher on AMC 12. Cutoffs and eligibility rules can change by cycle, so confirm them on the official MAA AMC page before planning around a particular score.

AMC 10 and AMC 12 are 25-question, 75-minute multiple-choice exams. AIME is a different format: 15 integer-answer problems, with answers from 000 through 999. Prepare for both the qualifying exam and the written-answer style that follows.

A practical 8-week AMC-to-AIME study plan

  1. Weeks 1–2 — diagnose. Take one timed, recent AMC paper. Sort missed and guessed questions by topic, then label each miss as a concept gap, setup error, arithmetic slip, or time choice.
  2. Weeks 3–4 — repair foundations. Rotate algebra, geometry, number theory, and counting. For each weak topic, learn one method, solve a short untimed set, then revisit it a few days later without looking at notes.
  3. Weeks 5–6 — build selection and pacing. Practice in timed blocks. Secure questions you can solve cleanly, mark uncertain ones, and return with remaining time. Do not spend half a contest forcing one problem.
  4. Weeks 7–8 — rehearse and review. Take full mocks under exam conditions. Spend at least as long reviewing as taking the test: reproduce each solution from a blank page and write down the clue you missed.

Use mocks to find repeatable patterns

A score is a snapshot; your review log is the study plan. Record the problem, the first point where your reasoning diverged, the correct idea, and a short cue for next time. Re-solve missed questions after a delay, then again a week later. If you only reread the solution, it can feel familiar without becoming retrievable.

For harder geometry questions, draw a clean diagram and mark equal lengths, angles, and cyclic relationships before choosing a theorem. For number theory, test small cases, identify a pattern, then prove why it continues. For counting, define exactly what one outcome represents before multiplying cases.

Avoid these preparation traps

Only taking full tests: repeated exposure without focused correction repeats the same mistakes. Studying only favorite topics: qualification rewards balanced reliability. Chasing a rumored cutoff: use the official threshold for your contest year and aim for a margin rather than planning around a historical score.

Once qualified, begin practicing integer-answer problems and writing complete reasoning. Use AMC work to strengthen fundamentals, then make AIME problems a regular part of your weekly practice.
