Frequently asked questions
Does the quiz require a database?
No. The question bank is generated by PHP, while progress is stored in the browser.
How are numerical answers checked?
Numerical questions use a small tolerance. Reasonable rounding is accepted when the question permits it.
Can I print a report?
Yes. Use the PDF or print button in the final report and choose a PDF printer.
How does mistakes-only mode work?
Incorrect question identifiers are saved locally. The mode creates a focused review from those questions.
What does partial credit cover?
Multiple-selection, ordering, and matching questions can earn partial credit based on correct elements.
Are chart questions interactive?
Yes. Plotly charts support hovering, zooming, panning, and responsive resizing.
Can progress be resumed?
Yes. Keep local saving enabled, then use the resume button after returning.
Does exam mode reveal answers immediately?
No. Exam mode hides immediate correctness feedback until the report is generated.
Can answer choices be shuffled?
Yes. Choice shuffling can be enabled without changing the correct stored answer.
