How the free quiz maker works with your PDF

Students with a stack of readings or lecture slides often want a quick way to test themselves before an exam. A free quiz maker for PDFs can read your own file and draft practice questions, so the quiz reflects what your course actually covers.

Questions are based on your own file, not a generic question bank.
Explanations show the reasoning behind each correct answer.
The free plan lets you study in the browser with no exports.
Paid plans add PDF, DOCX and Anki export, and Pro adds QTI 2.1 and Moodle XML.

Frequently asked questions

How many practice questions should I make for the American Civil War?

A set of 10 to 15 questions per reading is enough to test the main causes, battles and outcomes. Mix multiple-choice with short-answer questions so you practice recalling facts, not only recognizing them.

How can I study Civil War dates and battles more effectively?

Focus on cause and effect, such as why the Emancipation Proclamation changed the war's goals, instead of memorizing dates alone. Revisit missed questions after a day or two, because spaced review helps the timeline stick.

Is the free plan enough to make quizzes from PDFs?

The free plan includes 3 generations per month and studying in the browser. PDF and DOCX exports require the Plus plan, and QTI 2.1 and Moodle XML export require Pro.

Can I upload scanned pages or slides instead of a PDF?
