Changes made for Kwizzin.

We decoded text formatting, removed selected incomplete, unsuitable and time-sensitive entries, checked the multiple-choice structure, selected question pools, reordered answer options and arranged the questions into twenty topics with five fixed sets and four estimated difficulty bands.

The adapted question content is shared under CC BY-SA 4.0. You may reuse that content under the licence terms, including attribution and share-alike requirements. This licence notice applies to the question content, not automatically to Kwizzin branding, site code or design.

Editorial review.

The library has been screened for question structure and topic fit; not every fact has been independently verified. Difficulty is an estimate. If you spot an inaccurate, unclear or misplaced question, please contact us or email [email protected] with the topic, set and question number.
