FAQ
Quiz maker from PDF - practical questions
Q1
How big can the PDF be?
Focused documents - a chapter, a lecture deck, a report - give the sharpest questions. For a whole textbook, generate one quiz per chapter instead of feeding the entire file at once.
Q2
Can I quiz on just one chapter or section?
Yes - the simplest way is to upload only that chapter, or paste the section's text as your source, so every question stays inside the scope you chose.
Q3
What do wrong answers show?
Each miss displays an explanation of the correct answer drawn from your PDF, so the quiz teaches while it tests.
Q4
What kinds of questions does it write?
Multiple choice plus short-answer comprehension checks, placed where the material calls for them - and you can regenerate any question that doesn't fit.
Q5
How many quizzes can I make for free?
Sign-up includes 2 complete lessons - quizzes included - without a credit card, followed by a monthly free allowance. Upgrading costs $4.99/month and up on the yearly plan.
