# Thai Buddhist Studies Examination (Nak Tham)

This repository contains multiple-choice questions from the Thai Buddhist Studies
(Nak Tham) examination (2022, 2023). This dataset can be used for a benchmark for evaluating Large Language Models'
understanding of Thai Buddhist concepts and teachings.


## Dataset Statistics

| Year | Number of Multiple Choice Questions |
|------|-------------------------------------|
| 2022 | 1,400                              |
| 2023 | 1,350                              |

**Phra Udom thought on the exam:** We have reviewed the Nak Tham examination format and find it to be well-designed.
While it maintains a multiple-choice format, the questions go beyond mere memorization.
Instead, they require logical reasoning and inference skills to arrive at the correct answers.
The questions test the understanding of Buddhist principles through analytical thinking rather than rote learning.


## Data Collection Process

1. **OCR Extraction**: Questions were initially extracted from PDF examination papers using Optical Character Recognition (OCR)
2. **Data Structuring**: All questions were compiled and structured into a standardized CSV format
3. **Manual Verification**: The dataset underwent manual review and correction to ensure accuracy of text, choices, and correct answers
