What is the AMC 12?
The American Mathematics Competition 12 (AMC 12) is a high-school mathematics competition designed to challenge students with problems that require mathematical reasoning, creativity, and strong problem-solving skills.
Designed for High-School Students
The AMC 12 is intended for students in 12th grade and below. It provides an opportunity for high-school students to demonstrate mathematical knowledge and develop advanced problem-solving skills.
Challenging Mathematical Problems
The competition features 25 multiple-choice problems that progress in difficulty. Students are encouraged to think strategically and apply mathematical concepts rather than simply rely on routine calculations.
Builds Problem-Solving Skills
AMC 12 problems help students strengthen logical reasoning, mathematical creativity, pattern recognition, and analytical thinking. These skills can support preparation for advanced mathematics competitions and future STEM studies.
A Pathway to Advanced Competition
Strong performance in AMC competitions can provide students with valuable experience for the broader American Mathematics Competitions pathway and other high-level mathematics opportunities.
Competition Format & Key Details
Why AMC 12 matters: Beyond testing mathematical knowledge, AMC 12 encourages students to approach unfamiliar problems with persistence, strategy, and confidence — essential skills for advanced mathematics and STEM pathways.
AMC 12 Past Papers & Practice Resources
Prepare for the AMC 12 mathematics competition with past papers and practice resources. Working through previous AMC 12 problems can help students strengthen advanced mathematical reasoning, improve problem-solving skills, and become more confident when solving challenging competition-style questions.

AMC 12 Topics
AMC 12 problems draw from a broad range of high-school mathematics. Students should be comfortable applying mathematical concepts creatively and connecting ideas across different topics.
Algebra
Algebraic reasoning forms an important part of AMC 12 problem solving and often requires students to manipulate expressions and equations efficiently.
- Polynomials
- Equations & systems
- Factoring
- Algebraic identities
Geometry
Geometry problems test visualization, logical deduction, and the ability to recognize relationships between geometric objects.
- Triangles & polygons
- Circles
- Similarity & congruence
- Area & volume
Number Theory
Students encounter problems involving properties of integers, divisibility, remainders, and numerical patterns.
- Prime numbers
- Divisibility
- Factors & multiples
- Modular arithmetic
Combinatorics & Counting
Counting problems require students to organize possibilities carefully and identify efficient counting strategies.
- Permutations
- Combinations
- Counting principles
- Arrangements
Probability
Probability questions test logical thinking and the ability to calculate outcomes using systematic counting and probability principles.
- Basic probability
- Counting outcomes
- Conditional reasoning
- Expected values
Functions & Equations
Students may need to analyze functions, equations, transformations, and relationships between variables.
- Functions
- Quadratics
- Exponential expressions
- Functional relationships
Sequences & Series
Sequence problems challenge students to recognize patterns and derive relationships between terms.
- Arithmetic sequences
- Geometric sequences
- Recursive patterns
- Series
Inequalities
Inequality problems require students to compare quantities and identify bounds using algebraic and logical techniques.
- Linear inequalities
- Quadratic inequalities
- Bounds
- Optimization ideas
Coordinate Geometry
Coordinate methods combine algebra and geometry to solve problems involving points, lines, distances, and geometric relationships.
- Lines & slopes
- Distance & midpoint
- Coordinate transformations
- Geometric equations
Advanced Problem Solving
AMC 12 emphasizes creative mathematical thinking. Many problems require students to combine multiple concepts and discover efficient solution strategies.
- Logical reasoning
- Pattern recognition
- Strategic thinking
- Multi-step problems
Important: AMC 12 does not simply test individual formulas or standard textbook exercises. Problems often combine concepts from different areas of mathematics and reward students who can recognize patterns, reason efficiently, and approach unfamiliar problems creatively.
AMC 12 Registration Dates
Plan ahead for the AMC 12 by keeping track of important registration and competition dates. Registration is handled through authorized AMC competition administrators and participating institutions.
AMC 12 Important Dates
| Event | Date / Period | Information | Status |
|---|---|---|---|
| AMC 12 Registration | Check Current Year | Registration window announced annually | Registration |
| AMC 12 Competition | Check Current Year | Official competition date | Competition |
| Late Registration | If Offered | Availability may depend on administration | Varies |
Students generally participate through schools, educational organizations, or other authorized competition administrators.
Registration deadlines and competition dates can change from year to year. Always verify the dates for the specific AMC 12 competition year.
Planning tip: Students should begin preparing well before the registration deadline. Reviewing previous AMC 12 problems is an excellent way to become familiar with the competition's style, difficulty, and problem-solving strategies.
