I. Analysis of the 2025 AMC 10 Score Cutoffs

Trends of the Last 5 Years
Key Findings:
Significant Increase in Qualification Line: Rose from 93-96 points in 2021 to 105-108 points in 2025.
Intensified Competition for High Scores: The cutoffs for the top 5% and top 1% have also increased correspondingly, reaching historic highs especially in 2025.

Analysis of Underlying Reasons:
Surge in Participation: The number of participants continues to grow globally, especially among Chinese students, leading to fiercer competition.
Changes in Problem Style: Shifted from "calculation-focused" to "thinking-oriented and flexible," requiring students to possess stronger logical reasoning skills.
Increased Weight of AIME: Advancing to the AIME carries more weight, attracting more outstanding students to participate.

II. AMC 10 A vs. B: Which One to Choose?

01 Exam Focus and Difficulty Differences

AMC 10 A
Basic scores are key: The questions mostly involve "direct application of core knowledge points," with no overly tricky or unusual problems.
Features:
The first 15 questions are basic questions (accounting for 60% of the total score), suitable for candidates aiming to "secure basic scores and aim for medium scores."
Questions 16-20 are of medium difficulty.
The final 5 questions (21-25) have only a few challenging ones.

AMC 10 B
High-level questions determine the gap: The questions focus more on "higher-order thinking and comprehensive problem-solving strategies." Challenging questions (19-25) account for a higher proportion and often require unconventional methods.
Features:
The proportion of basic questions is reduced, with a tighter connection between medium and challenging questions.
Suitable for candidates with "solid fundamentals aiming for the top 5% or top 1%."

02 Score Cutoff Differences

The difficulty levels of the A and B versions are similar, but some questions on the B version are more challenging.
Historical data shows that the qualification line for version B is generally higher than for version A, but overall fluctuations are minimal.

03 How to Choose?

Exam Schedule: Version A is usually one week earlier than Version B (estimated to be November 6 and November 14, 2026).

Difficulty and Focus:
Version A focuses more on applying math to real-world scenarios and computational problem-solving.
Version B emphasizes a balanced assessment across various areas, with some questions being more flexible and requiring higher mathematical literacy.

Strategic Advice:
If conditions permit, it is recommended to take both exams. Your highest score will be counted.
If you can only take one, you can first familiarize yourself with the question types by looking at past Version A papers before making a decision.

III. 2026 AMC 10 Preparation Strategy

Foundation Stage (6 months in advance)
Core Goal: Focus on Algebra (main score driver) + Number Theory (strength area for points), thoroughly grasp intermediate geometry problems, and cover basic combinatorics question types.
Specific Steps: Work through questions 1-22 of past 10 years of exams 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 errors per module to ≤5%, ensuring you can immediately see the approach for intermediate questions (11-20).

Advanced Stage (3 months in advance)
Core Goal: Take full-length timed mock exams (75 minutes), practice time allocation and answering strategies.
Ideal Pacing:
Questions 1-10: ≤18 minutes (aim for all correct)
Questions 11-20: ≤32 minutes (at most 1 wrong)
Questions 21-25: ≤20 minutes (aim for 2-3 correct)
Last 5 minutes for review
Study Schedule: Complete 3 sets of A/B version past exams from the last 5 years each week, reviewing mistakes on the same day and patching frequent weak points.

Sprint Stage (1 month before the exam)
Core Goal: Let go of overly tricky problems, return to high-frequency topics and core formulas.
Specific Steps:
Review your error notebook and high-frequency questions from past 3 years of exams.
Memorize geometry/number theory shortcut formulas.
Practice classic question types from questions 21-25.
Establish consistent answering habits (circle keywords in questions, avoid reading/computation errors).

AMC10 Knowledge Points Fully Explained! Question Distribution & Difficulty Levels – How Long to Prepare for an Award?

The AMC10 is an international mathematics competition organized by the Mathematical Association of America (MAA) for students in grade 10 and below. Its content covers all middle school and first-year high school math knowledge, with higher requirements in certain areas such as number theory and combinatorics. This article will provide a detailed analysis of the AMC10's knowledge point distribution, difficulty levels, and preparation strategies to help you scientifically plan your preparation path.

II. AMC10 Question Distribution & Difficulty Levels

Basic Questions (Questions 1-8)
Relatively low difficulty, covering basic knowledge points in algebra, geometry, and number theory.
Goal: answer all correctly, ensuring accuracy and speed to save time for the harder questions later.

Relatively Easy Questions (Questions 9-13)
Slightly higher difficulty, mainly reflected in traps and pitfalls within the problem statements.
Requires careful reading. These are questions that most students can master.

Medium Difficulty Questions (Questions 14-17)
This is the watershed—the key to achieving the top 1%.
For Grade 8 and below students, correctly answering 15 questions is already excellent. For Grade 9+ students, these must be tackled intensively, aiming for a perfect score.

Harder Questions (Questions 18-23)
Relatively difficult. Beyond basic techniques, these introduce advanced concepts such as linear functions, quadratic equations, and probability and statistics.
This is the key breakthrough area for students aiming for the top 5% and AIME qualification cutoffs.

Difficult Questions (Questions 24-25)
The true difficult questions, demanding deep knowledge and sharp thinking agility.
Only a very small proportion of students can complete these. Students aiming for a perfect score should focus on breaking through here.

III. AMC10 Preparation Timeline & Strategies

1. Foundation Building Phase (Recommended: 6-8 months in advance)
Goal: systematically review AMC10 knowledge points across all sections, expanding beyond standard school mathematics.
Approach:
– For beginners and lower-grade students: spend at least six months building a solid foundation.
– Review school-level knowledge: ensure no major weaknesses in the four core modules (Algebra, Geometry, Number Theory, Combinatorics).
– Supplement competition-specific content: e.g., congruence equations in Number Theory, recurrence relations in Combinatorics.

2. Practice Phase (2-3 months before the exam)
Goal: improve problem-solving speed and accuracy through intensive practice with real exam papers.
Approach:
– Study past years' exams: become familiar with how each knowledge point is applied in test questions.
– Connect knowledge modules across topics: train flexible problem-solving approaches.
– Keep an error log: systematically address your own weaknesses.

3. Sprint Phase (1-2 months before the exam)
Goal: comprehensively enhance exam-taking skills to ensure optimal performance on test day.
Approach:
– Targeted assault on difficult areas: intensive training on weak points.
– Comprehensive review of knowledge points: fill in any remaining gaps.
– Repeated practice of past mistakes: ensure errors are not repeated.
– Mock exams: strictly timed simulations of the real test environment.
– Time management training: improve answering speed and allocate time appropriately per question.
