Dataset description

This dataset was presented and described further on FedCSIS 2025 conference and the full paper can be found here: https://annals-csis.org/proceedings/2025/pliks/2608.pdf

The dataset is a collection of image-based questions sourced from Polish National Exams. Each question is represnted in the form of an image with only one correct answer. The questions distribution is described in the table below:

Exam Discipline Questions
8th-Grade Exam Polish Language 9
8th-Grade Exam Mathematics 46
Middle School Exam Mathematics and Nature 152
Middle School Exam Mathematics 96
Middle School Exam Nature 79
High School Exam Biology 21
High School Exam Physics 154
High School Exam Mathematics 280
Professional Exam Arts 2547
Professional Exam Mechanical, Mining and Metallurgical 21057
Professional Exam Agriculture and Forestry 14905

Manual verification revealed that 122 of the 1,000 images were misclassified in needs_image_context question metadata, with the vast majority being false positives (120 out of 122). While this level of error is acceptable for exploratory analysis and broad grouping, it is not sufficiently accurate for training downstream models. We therefore emphasize that findings based on this stratification are preliminary and should not be overinterpreted without more precise annotation.
