# Korean DeepMath with Difficulty

This dataset enriches `ChuGyouk/Korean-DeepMath` with difficulty and topic metadata from `zwhe99/DeepMath-103K`.

## Join procedure

Rows are matched using `Korean-DeepMath[extra_info][index]` -> original DeepMath row index.

## Added fields

- `original_index`
- `difficulty`
- `topic`

## Intended use

Prepared for controlled Korean mathematical reasoning SFT experiments, including difficulty-aware sampling such as TDCS.

No Easy / Medium / Hard labels are added here. Bucket boundaries should be selected after analyzing the difficulty distribution.
