# HMMT-Nov-2025


## Overview

HMMT November 2025 (MathArena) is a challenging evaluation benchmark derived from the Harvard-MIT Mathematics Tournament (HMMT) November 2025 competition, one of the most prestigious and difficult high school math contests globally. It is a different contest from HMMT February 2025 (`hmmt25`).

## Task Description

- **Task Type**: Competition Mathematics Problem Solving
- **Input**: HMMT-level mathematical problem
- **Output**: Answer with step-by-step reasoning
- **Domain**: Algebra, Combinatorics, Geometry, and Number Theory

## Key Features

- 30 problems from the HMMT November 2025 competition
- Sourced from the MathArena `hmmt_nov_2025` dataset and mirrored on ModelScope
- Highly challenging competition-level problems
- Tests advanced mathematical reasoning
- Represents elite high school mathematics difficulty

## Evaluation Notes

- Default configuration loads `evalscope/hmmt_nov_2025` from ModelScope and evaluates the `train` split
- Default configuration uses **0-shot** evaluation
- Answers should be formatted within `\boxed{}` for proper extraction
- Numeric accuracy uses mathematical equivalence checking for integers, fractions, decimals, and symbolic expressions
- No additional runtime dependencies are required

```

## Usage

### Using CLI

```bash
evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets hmmt_nov25 \
    --limit 10  # Remove this line for formal evaluation
```

### Using Python

```python
from evalscope import run_task
from evalscope.config import TaskConfig

task_cfg = TaskConfig(
    model='YOUR_MODEL',
    api_url='OPENAI_API_COMPAT_URL',
    api_key='EMPTY_TOKEN',
    datasets=['hmmt_nov25'],
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
