MATH Level 5 is the most challenging subset of the MATH dataset, a comprehensive benchmark for evaluating mathematical reasoning capabilities in artificial intelligence systems. Created by Dan Hendrycks and colleagues at UC Berkeley, University of Chicago, and OpenAI in 2021, MATH Level 5 consists of the most difficult competition-level mathematics problems from the full MATH dataset of 12,500 problems. These problems require advanced mathematical reasoning and problem-solving skills that go beyond standard K-12 mathematics tools.

Overview

MATH Level 5 represents the pinnacle of difficulty within the MATH dataset's five-tier difficulty system. While the complete MATH dataset contains 12,500 problems (7,500 training and 5,000 test), Level 5 specifically isolates the most challenging problems that test the limits of both human and machine mathematical reasoning capabilities. These problems are drawn from prestigious mathematics competitions including the AMC 10, AMC 12, and American Invitational Mathematics Examination (AIME).

Significance

The creation of MATH Level 5 addresses a critical need in AI evaluation: measuring genuine mathematical reasoning rather than pattern matching or memorization. Unlike many benchmarks that can be solved through scaling alone, MATH Level 5 requires fundamental algorithmic advances to achieve high performance. The benchmark has revealed that simply increasing model parameters is insufficient for solving complex mathematical problems[1].

Problem Characteristics

Difficulty Classification

The MATH dataset employs a five-level difficulty system where:

Level Description Typical Problem Type
Level 1 Easiest problems for humans Basic arithmetic and algebra
Level 2 Elementary problems Simple word problems
Level 3 Intermediate difficulty Multi-step reasoning
Level 4 Advanced problems Complex competition problems
Level 5 Hardest problems Elite competition-level challenges

Level 5 problems are specifically selected to represent the most challenging questions that appear in high school mathematics competitions, requiring sophisticated problem-solving strategies and deep mathematical understanding. The exact number of Level 5 problems within the dataset has not been independently verified in available sources.

Subject Distribution

MATH Level 5 problems span seven mathematical domains:

Subject Description Example Topics
Algebra Algebraic manipulation and equations Polynomial equations, systems of equations
Counting & Probability Combinatorics and probability theory Permutations, combinations, expected values
Geometry Euclidean and coordinate geometry Circle theorems, trigonometry, transformations
Intermediate Algebra Advanced algebraic concepts Complex numbers, sequences, functions
Number Theory Properties of integers Divisibility, modular arithmetic, prime numbers
Prealgebra Foundational mathematics Fractions, ratios, basic operations
Precalculus Pre-calculus mathematics Logarithms, exponentials, trigonometric identities

Problem Sources

Competition Origins

MATH Level 5 problems are sourced from prestigious mathematics competitions:

Competition Full Name Target Audience
AMC 10 American Mathematics Competition 10 High school students grade 10 and below
AMC 12 American Mathematics Competition 12 High school students grade 12 and below
AIME American Invitational Mathematics Examination Top AMC performers
Other Various regional and national competitions Advanced high school students

These competitions represent decades of curated problems designed to identify and challenge the most talented young mathematicians in the United States and internationally.

Problem Format

Each problem in MATH Level 5 includes:

  • **Problem Statement**: Written in LaTeX format for precise mathematical notation
  • **Step-by-Step Solution**: Detailed solution showing the reasoning process
  • **Final Answer**: Exact numerical or algebraic answer
  • **Metadata**: Subject classification and difficulty level

Evaluation Methodology

Scoring System

The primary evaluation metric for MATH Level 5 is exact match accuracy:

Metric Description Calculation
Accuracy Percentage of correctly solved problems (Correct answers / Total problems) × 100%
Exact Match Answer must match exactly No partial credit given
Pass@k Success rate with k attempts Percentage solved within k tries

Answer Verification

Answers are evaluated using strict matching criteria:

  • Numerical answers must be exact (within floating-point precision)
  • Algebraic expressions must be equivalent
  • Multiple representations of the same answer are accepted
  • No partial credit for incomplete or approximate solutions

Performance Analysis

Human Performance

Population Estimated Performance Notes
Graduate Students ~35-40% PhD students in technical fields (estimated)
Undergraduate Math Majors ~30-35% Upper-division mathematics students (estimated)
High School Competitors Variable Depends on competition experience
General Population <10% Without specialized training

The estimated 35-40% accuracy achieved by graduate students highlights the exceptional difficulty of Level 5 problems, which require not just mathematical knowledge but creative problem-solving abilities. Note that exact human performance figures have not been independently verified in published sources.
