The 2026 AMC8 has undergone its biggest reform in five years! The exam time has been adjusted from the morning to the afternoon from 17:00 to 17:40, which better suits the daily routines of Chinese students. Two new global individual awards have been added: Top 10% and Top 25%, giving more students the chance to gain international recognition. The scoring standards have also become more detailed: key theorem numbers must be indicated in the solution steps, and process points account for up to 30% of the score. This means that having the correct answer alone is no longer enough; clear problem-solving reasoning is equally important.
I. 2026 Registration Guide
The registration deadline is January 13, 2026, and the exam will be held on January 23. The registration fee is 120 RMB per person. Registration is done collectively by schools or authorized agencies; individual direct registration is not allowed.
The main registration channels include: first, group registration through full-time schools that have been certified as test centers; second, proxy registration through officially authorized agencies. For registration, you need to prepare a scanned copy of your ID card or passport, an electronic ID photo, and proof of current grade.
Summary of Key Registration Information:
| Registration Method | Target Audience | Specific Steps |
|---|---|---|
| School Group Registration | Students whose school is an official AMC8 partner test center | Registration is organized centrally by school teachers |
| Agency Proxy Registration | Students whose schools are not test centers | Proxy registration through officially authorized third-party educational institutions |
II. New Syllabus Changes
While the 2026 AMC8 retains the same format of 25 multiple-choice questions, the question design places a stronger emphasis on interdisciplinary applications and advanced logical reasoning. The geometry module introduces dynamic analysis of 3D nets, while the algebra and probability sections incorporate real-world scenario modeling problems, such as "supermarket promotion models" and "quadratic function carbon emission modeling."
The specific distribution of each module is as follows:
Distribution and Key Content of the Four AMC8 Modules (2026)
| Module | Percentage | Core Topics |
|---|---|---|
| Algebra & Probability | 40%–45% | Real-world scenario modeling (e.g., supermarket promotion models, carbon emission optimization), quadratic function applications, probability integrated with business contexts. |
| Geometry | 25%–30% | Dynamic analysis of 3D nets, Pythagorean theorem applications in building structures, area calculations of irregular shapes. |
| Number Theory & Combinatorics | 20%–25% | Prime factorization, divisibility rules, GCD/LCM using short division, sum of geometric sequences. |
III. Key Difficulties and Strategies
Algebra Module: The algebra module has the largest number of questions, focusing on basic operations and applied problem-solving. Ratio and fraction calculations account for 6-9 questions, often involving multi-step percentage conversions; equations and word problems account for 3-6 questions, focusing on speed-time-distance relationships in travel problems and engineering efficiency models. The new quadratic function modeling and probability problems introduced in 2026, such as carbon emission optimization problems and supermarket promotion discount problems, require students to have the ability to apply mathematical knowledge to real-life situations.
Geometry Module: The geometry module emphasizes spatial thinking and the flexible use of formulas, and is key to differentiating students. Triangle properties involve the Pythagorean theorem and similarity criteria, accounting for 2-4 questions; perimeter and area calculations of circles and polygons account for 1-3 questions. The newly added dynamic analysis of 3D nets requires students to have good spatial imagination, such as problems about the unfolding path of a packaging box.
Number Theory & Combinatorics Module: The weight of number theory and combinatorics continues to rise, with a focus on prime factorization and divisibility properties. The number theory section in 2026 has increased in difficulty, requiring mastery of short division to efficiently find the least common multiple (LCM) and greatest common divisor (GCD), with prime factorization involving the rapid decomposition of large numbers.
IV. High-Score Tips
Time management is the key to success in the AMC8. You have 40 minutes to complete 25 questions, averaging only 1 minute and 36 seconds per question. A recommended layered problem-solving strategy is:
Basic level (Questions 1–10): Limit to 8 minutes, aiming for 100% accuracy.
Intermediate level (Questions 11–20): Allocate 15 minutes, making good use of the substitution of special values method.
Challenge level (Questions 21–25): Reserve 17 minutes, prioritizing combinatorial counting or geometry transformation problems.
Core problem-solving techniques include:
Proof by Contradiction: For existence propositions.
Inclusion-Exclusion Principle: To solve overlapping counting problems.
Dynamic Graphing Method: Quickly sketch extreme cases when you have no clear idea in a geometry problem.
Paper-Folding Experiment Method: For 3D geometry problems, use scratch paper to create a simple model to aid understanding.
Avoiding common traps can also effectively boost your score. The traps that 90% of test-takers often fall into include:
Misreading the problem: For example, confusing "growth rate" with "growth amount."
Calculation errors: Skipping steps leading to sign errors.
Fixed thinking patterns: Ignoring multiple possible configurations in geometry problems.
Circling keywords while reading, writing intermediate steps separately, and underlining key results in complex calculations can all effectively reduce errors.
V. Sample Problems
Below are typical questions that illustrate the style of the AMC8:
Algebra Example: The product of two positive integers is 24, and their sum is 11. Find the larger number. The solution approach is to set the two numbers as x and y, list the equations xy=24 and x+y=11, solve to get x=8, y=3, so the larger number is 8. This problem tests integer factorization and the concept of quadratic equations.
Geometry Example: Isaiah cuts open a cube, and the area of its net is 18 cm². Find the volume of the original cube. The solution approach is: a cube has 6 faces, and the area of the net is 18 cm², so the area of each face is 3 cm². The edge length is √3 cm, and the volume is (√3)³ = 3√3 cm³. This problem tests the ability to convert between 3D and 2D representations.
Number Theory Example: Remove one number from 15, 16, 17, 18, 19 so that the sum of the remaining four numbers is a multiple of 4. Find the number that was removed. The key to solving is to calculate the total sum of the five numbers: 85, which leaves a remainder of 1 when divided by 4. Therefore, you need to remove a number that also leaves a remainder of 1 when divided by 4, which is 17. This problem tests the ability to determine divisibility properties of integers.
