As a highly recognized international mathematics competition, the AIME (American Invitational Mathematics Examination) invites students who have successfully passed the qualification cutoff in the AMC 10/12. Serving as a prerequisite for the USA(J)MO, the AIME carries significant academic weight. For students aiming to apply to top 30 STEM programs, a strong AIME score is undoubtedly a major advantage.
Recently, the qualification scoring system for the USA(J)MO has been adjusted, with the weight of AIME scores increasing. This means that achieving an excellent AIME score will play an even more critical role in the advancement process. How exactly has the cutoff score changed? How should students prepare to achieve high scores? Read on for a comprehensive guide.
New Changes in USA(J)MO Qualification Scoring
Students who achieve high scores in the AMC 12 and AIME will be invited to the USAMO, while those with high scores in the AMC 10 and AIME will be invited to the USAJMO.
The qualification cutoff score for the USA(J)MO has changed from the previous formula: AMC Score + AIME Score × 10 to AMC Score + AIME Score × 20.
- USAMO Standard Score = AMC 12 Score + 20 × AIME Score.
- USAJMO Standard Score = AMC 10 Score + 20 × AIME Score.
Example: If a student scores 110 on the AMC 12 and 12 on the AIME, their USAMO qualification score would be: 110 + (12 × 20) = 350.
Note: Students with Chinese citizenship can only compete up to the AIME level and are not eligible for the USA(J)MO. Only U.S. citizens or students studying in the U.S. and Canada are eligible to participate in the USA(J)MO. However, reaching the USA(J)MO qualification cutoff remains a strong testament to a student's academic ability.
Based on recent years' cutoff scores, to qualify for the USAMO or USAJMO, students generally need to score at least 110 to 120+ on the AMC 10/12 and correctly answer at least 11 questions on the AIME.

The American Invitational Mathematics Examination (AIME) is a crucial step in the U.S. Mathematical Olympiad selection system. It aims to identify students with exceptional mathematical abilities and lay a solid foundation for their future competition and research endeavors.
Eligibility
Students in grade 12 or below who have qualified through the AMC 10/12 in the same competition year.
2025 AIME Qualification Cutoff Scores:
| Competition | Cutoff Score |
|---|---|
| AMC 10 A | 93 |
| AMC 10 B | 94.5 |
| AMC 12 A | 85.5 |
| AMC 12 B | 88.5 |
Competition Dates
AIME I: February 6, 2026, 13:00-16:00 (Tentative)
AIME II: February 12, 2026, 13:00-16:00 (Tentative)
Registration Process
After qualifying through the AMC 10/12, candidates will receive an official email or SMS notification. Students must log in to the official registration portal (AMC China or ASDAN) to confirm their participation in the AIME.
Competition Format
Format: Individual competition, 15 questions. All answers are integers between 0 and 999.
Duration: 180 minutes.
Scoring: Total of 15 points. 1 point for each correct answer, 0 points for blank or incorrect answers.
Tested Topics
The exam covers four main areas: Algebra, Geometry, Combinatorics & Probability, and Number Theory.
Specific topics include Vieta's formulas and applications of higher-degree equations, functional inequalities and basic abstract functions, trigonometric forms of complex numbers and geometric transformations in the complex plane, sequence construction and sequences with Diophantine equations, similarity transformations combining triangles and circles, cyclic quadrilaterals, power of a point theorem combined with sine and cosine laws, special triangle theorems (Stewart's theorem, Shoelace theorem, etc.), combinatorial methods and recursive thinking, classical and geometric probability models, divisibility and congruence concepts, number systems and base conversions, floor functions, and comprehensive applications of fundamental number theory theorems, prime factorization, LCM/GCD, and solving Diophantine equations.
The Value of the AIME Competition
1. Enhances College Applications
Adding AIME participation and strong scores to an application resume leaves a lasting impression on admissions officers. Participating in the AIME and AMC not only demonstrates exceptional mathematical ability but also showcases a student's perseverance and dedication to mathematics, significantly boosting their chances of admission to dream schools.
For instance, prestigious U.S. universities such as Stanford, MIT, and Carnegie Mellon University explicitly ask applicants to report their AMC/AIME scores on their application portals.
2. Comprehensively Tests and Develops Mathematical Thinking
The AIME goes beyond mere calculation skills; it rigorously tests logical reasoning and problem-solving abilities. Through the AIME's selection process, students encounter diverse mathematical challenges that strengthen their ability to apply mathematical knowledge effectively.
Preparing for and taking the AIME helps students gain a deeper understanding and application of mathematical concepts and methods, providing a crucial foundation for future university-level mathematics studies.
AIME Question Difficulty Breakdown
Questions 1-5
These are the foundational questions. The tested concepts fall strictly within the core knowledge scope of the AMC 10/12, such as analytic geometry and equation solving.
Questions 6-10
These represent the medium-difficulty section. The difficulty increases noticeably compared to the first five questions. Students must quickly grasp the tested concepts, break down the given conditions, and efficiently find the optimal solution. Topics often include combinatorial counting and spatial geometry.
Questions 11-15
These are the highly challenging final questions. They typically require integrating knowledge from multiple modules to solve.
Compared to the AMC 10/12, the AIME covers a narrower range of topics but delves much deeper into each concept, significantly increasing the overall difficulty.
AIME Preparation Strategies
Targeted Practice
Solidify your foundation with targeted exercises. Supplement your knowledge by studying advanced topics not covered in the AMC, and complete specialized problem sets to build proficiency.
Past Paper Training
Begin practicing with past AIME papers 2-3 weeks before the exam. Complete the papers under timed conditions. This helps you familiarize yourself with the difficulty distribution, develop problem-solving intuition, and adapt to the exam's rigor. Timed practice also allows you to gauge your pacing, allocate time effectively across questions, and maximize your performance within the limited exam window.
