## Dataset Description

This dataset contains questions from the Konkur (Iranian University Entrance Exam) for the year 1404. It is designed for evaluating models on Persian multiple-choice questions across various subjects.

### Dataset Summary

- **Total Examples**: 2137
- **Splits**: train
- **Languages**: Persian (fa)

## Dataset Structure

### Data Instances

An example from the dataset looks like this:

```json
{
  "id": "ensani_nobat1_1",
  "exam_name": "ensani_nobat1",
  "question": "اگر شعاع دایره شکل زیر برابر $x = \\frac{1}{\\sqrt{2\\pi}}$ و مجموع مساحتهای دو شکل برابر ۱۶ باشد، محیط دایره کدام است؟",
  "choices": [
    "$\\sqrt{\\pi}$",
    "$2\\sqrt{\\pi}$",
    "$3\\sqrt{\\pi}$",
    "$4\\sqrt{\\pi}$"
  ],
  "answer_key": 4,
  "figure": "<Image: PNG, (437, 231)>"
}
```

- **choices** (List(Value('string'))): Description of choices.
- **answer_key** (int32): Description of answer_key.
- **figure** (PIL.Image.Image): Description of figure.

## Dataset Statistics

### Split: train

## Evaluation with OpenAI-Compatible API

- Deterministic settings (temperature=0) are recommended.
- Normalize Persian digits and English number words.
- Report both overall accuracy and per-exam accuracy.
- Use multimodal input for questions with figures if your model supports images.

### Data Notes

- Choices are always 4 options; answer_key is 1–4 (1-based).
- Figures are PNGs referenced by relative paths; when loaded via HF Datasets, figure may be an image object.
- Text may include LaTeX-style math and Persian digits; normalize for robust parsing.

### Ethics and Usage

- For evaluation and research use; respect exam policies and local regulations.
- Random baseline is 25% accuracy; report per-exam breakdown for interpretability.
