Example: a quiz from the Declaration of Independence
Three questions of the kind a public domain PDF turns into. A full quiz has 10.
- According to the Declaration, where do governments get their just powers? (a) The king (b) The consent of the governed (c) Divine right (d) Military strength
- (b) The consent of the governed. The Declaration argues that a government's authority comes from the people it governs.
- Which unalienable rights does the Declaration name? (a) Speech, press and religion (b) Life, liberty and property (c) Life, Liberty and the pursuit of Happiness (d) Equality, justice and peace
- (c) Life, Liberty and the pursuit of Happiness. "Property" is a common mix-up, because it comes from John Locke's earlier wording.
- What fills most of the Declaration's long middle section? (a) A plan of government (b) A list of grievances against the King (c) A bill of rights (d) A peace treaty
- (b) A list of grievances against King George III, laid out to justify breaking away from Britain.
Best PDFs for a practice quiz
Lecture slides before a test
Export the slides to PDF and quiz yourself on each lecture. Slides are light on words, so a lecture often fits in one run.
Textbook chapters
Save the chapter as its own PDF. A quiz per chapter shows which ones need another look.
Study guides
Upload a study guide and turn its topics into questions you actually have to answer.
Scanned PDFs and long files
The quiz is written from the text layer of your PDF. Typed documents and exported slides have one. Scans and photos of pages don't, and the tool can't read them.
Each run uses about the first 15,000 characters of the file, around 2,500 words. If your PDF is a whole book, save the chapter you need as a separate PDF first. You'll get sharper questions from a focused chunk anyway.
Why quiz yourself instead of rereading
Answering a question forces you to recall, and recall is what makes memory stronger. It also shows you the gaps rereading hides: a page can feel familiar while the answer is still out of reach. Getting a question wrong and then reading why is one of the fastest ways to close a gap.
For the long run, space it out and quiz yourself again a few days later. In the full lezrn app, your PDF becomes a course, and reviews are scheduled for you so each idea comes back right before you'd forget it.
