1. The "Golden Key" to Ivy League & G5

Recent admission data shows: over 45% of Ivy League/Oxbridge engineering and science admits have AMC participation experience; MIT, Stanford, Cambridge, and others explicitly value AMC/AIME scores in the Common App; AMC10 top 1% (DHR) ≈ an international math proficiency certification, far surpassing ordinary high school grades.

2. A Screening Tool for Domestic Elite High School "Science Classes"

No.2 High School of East China Normal University, Shanghai High School, Fudan University High School: AMC10 score of 110+ can lead to direct interview; Qibao High School, Jianping High School, Nanyang Model High School: top 25% (approx. 100 points) get priority in independent enrollment, with some "score cut-off equals admission"; Guanghua Cambridge International School's entrance exam: Question 9 directly uses an original AMC10 problem; even World Foreign Language School tests up to AMC12 difficulty.

3. The "First Building Block" of the International Competition Pyramid

Top 2.5% (approx. 103–110 points) → qualifies for AIME; high AIME scores → USAMO → IMO national team; AMC10 is the starting point to IMO and a necessary path for most international competition participants.

4. Skill Enhancement: Highly Aligned with IB/AP/A-Level

The problems emphasize logical reasoning, modeling skills, and creative problem-solving; highly overlapping in content with IB Math AA/AI, AP Calculus, and A-Level Further Math; preparation can feed back into school grades, achieving a "competition + coursework" win-win.

5. Globally Recognized, Certificate Valid for Life

Officially issued by the MAA, widely recognized by global universities, summer schools, and research programs; a high score serves as a lifelong proof of academic ability.

1. Immense Time Pressure

75 minutes / 25 questions = average 3 minutes per question; the first 15 questions need to be completed within 30 minutes, leaving sufficient time for the last 10 questions (especially the challenging 21–25); beginners often fail to even look at the challenging questions due to slow reading, slow calculation, or indecision.

2. Intense Global Competition

Over 30,000 participants globally each year, but only about 300 achieve top 1%; students from China, South Korea, India, and elsewhere are systematically trained—the era of taking the test unprepared is over; cutoff scores are rising: DHR has stabilized at 130+ points (out of 150) in recent years.

3. Dense Problem Traps

AMC10 is known for being "deceptively simple, but hiding pitfalls": unit confusion, ignoring boundary conditions, graphic misdirection (non-standard diagrams). Many students "feel they got it right, but the answer is wrong," fundamentally due to shallow understanding and imprecise thinking.

4. Extremely Low Margin for Error

130 points ≈ at most 1–2 mistakes; moreover, at least 3–4 of questions 21–25 must be correct (each worth 6 points, determining DHR qualification); this means not only must the foundation be solid, but advanced thinking must be exceptionally strong.

01 Focus and Difficulty Differences

AMC10 A
Basic points are key: Questions are mostly "direct applications of core knowledge points," without obscure or weird questions.
Features:
The first 15 questions are basic (accounting for 60% of the total score), suitable for test-takers who want to "secure basic points and aim for medium-level points."
Questions 16-20 are medium difficulty.
Only a few advanced questions among 21-25.

AMC10 B
Advanced questions determine the gap: Places more emphasis on "higher-order thinking and comprehensive problem-solving strategies," with a higher proportion of difficult questions (19-25), requiring unconventional methods to solve.
Features:
Reduced proportion of basic questions, with a tighter connection between medium and difficult questions.
Suitable for test-takers with "solid fundamentals aiming for top 5%/top 1%."

02 Score Differences

A and B versions have similar difficulty levels, but some questions in B are more challenging.
Historical data shows that the qualification cutoff for B is generally higher than that for A, but the overall fluctuation is small.

03 How to Choose?

Exam Time: A is usually one week earlier than B (expected to be November 6 and November 14, 2026).
Difficulty and Focus:
A focuses more on the application of mathematics in real scenarios and computational solving.
B emphasizes a balanced examination across different areas, with some questions being more flexible and requiring higher mathematical literacy.
Strategic Advice:
If conditions permit, it is recommended to take both exams and use the higher score.
If only one can be taken, you can first refer to A's past papers to familiarize yourself with the question types before making a choice.

1. Foundation Phase (6 months in advance)

Core Goal: Focus on Algebra (main scoring subject) + Number Theory (advantageous for scoring), thoroughly understand medium-level Geometry problems, and grasp basic Combinatorics question types.
Specific Steps:
Practice questions 1-22 of past papers from the last 10 years by module, summarizing quick problem-solving techniques for each module (e.g., substitution in algebra, auxiliary lines in geometry, congruence simplification in number theory).
Keep the error rate per module ≤5%, ensuring immediate idea generation for medium-level questions (11-20).

2. Advanced Phase (3 months in advance)

Core Goal: Full-length timed mock exams (75 minutes) to practice time allocation and answering strategies.
Golden Rhythm:
Questions 1-10: ≤18 minutes (get all correct)
Questions 11-20: ≤32 minutes (≤1 error)
Questions 21-25: ≤20 minutes (aim for 2-3 correct)
Last 5 minutes: review
Study Plan:
Complete 3 sets of A/B past papers from the last 5 years per week, review errors on the same day, and fill in high-frequency gaps.

3. Sprint Phase (1 month before the exam)

Core Goal: Abandon obscure and weird questions, return to high-frequency topics and core formulas.
Specific Steps:
Review error notebooks + high-frequency questions from the last 3 years of past papers, memorize quick calculation formulas for Geometry/Number Theory, and practice classic question types from questions 21-25.
Establish consistent answering habits, circle keywords in questions, and avoid reading/computation errors.
