How to generate a quiz from a PDF of your notes

Why does testing yourself beat rereading your notes?

Rereading feels productive because the text becomes familiar, and familiarity is easy to mistake for knowledge. Answering a question does the opposite. Your memory has to retrieve the information with nothing in front of you, and that retrieval effort, known as the testing effect, is what makes the memory stick. A quiz built from your own PDF turns passive reading into a sequence of active recalls.

The second benefit is diagnostic. While you reread, the page keeps feeding you the answers, so you never find out what you do not know. A quiz gives you a precise list of weak points in ten minutes, and that list becomes the plan for your next session.

How do you generate a quiz from a PDF?

You upload the PDF to a quiz generator, choose how many questions you want and at what difficulty, and the tool reads the document to pull out what can be tested. On Study-Genie the questions come only from your file: the definitions, formulas, dates and mechanisms that appear in that specific set of notes. Every answer is marked and comes with an explanation, so a mistake teaches you something.

PDFs are not the only input. A Word document, a lecturer's slide deck, a photo of handwritten notes read by optical character recognition, an audio recording of the lecture that gets transcribed, or plain pasted text all work the same way. The app runs on the web and on mobile, iOS and Android, so a quiz you generate in the evening can be retaken on the bus.

What makes a good revision quiz?

A good quiz tests one idea per question, and the question makes sense without the notes open beside you. The wrong answers are not absurd: they are mistakes you could genuinely make, such as the neighbouring formula, the date that is one year off, or the cause swapped with the effect. Each question ends with an explanation of the correct answer, otherwise you memorise a result without understanding it.

One detail often gets overlooked: the order of the questions. Mixing topics instead of following the order of the chapter stops your memory from leaning on the previous page for context, which makes the score a fairer prediction of exam day.

• One idea per question — if you cannot tell which of two concepts tripped you up, the question was testing two.
• Plausible distractors, drawn from the confusions that chapter usually causes.
• An explanation after marking, not just right or wrong.
• Short stems, so the difficulty is in the answer rather than in the wording.
• Adjustable difficulty — easy to check the basics, hard the night before the exam.

How should you prepare a PDF before generating a quiz?

The quiz is only as good as the document. A clean text PDF gives the best results, and scanned notes work too as long as the photo is sharp, flat and evenly lit. Split a hundred-page handbook into chapters: a quiz on one section of the syllabus is sharper and more useful than a quiz that skims a whole term.

Slide decks need extra care. Lecture slides often carry headings and keywords without the sentences the lecturer actually said, so the questions risk staying shallow. Add your own notes, or upload the audio recording of the session alongside the deck.

• Scanned notes — photograph page by page, with no shadow or thumb across the text.
• Chapter too long — split it along the syllabus headings, one quiz per part.
• Slide decks — pair them with your notes or the lecture recording.
• Cover pages, bibliographies and appendices add nothing, so leave them out.

How many questions should a chapter have?

Ten to fifteen questions cover an ordinary chapter, and twenty to thirty suit a big topic you are revising for A-levels or finals. Past that, the session drags and your attention drops before the end, which makes the last mistakes meaningless. Three sets of fifteen spread across the week beat one set of fifty taken once, the night before.

Repetition matters more than volume. The first set is a diagnosis, a second one two days later checks what survived, and a third before the exam locks it in. That is spaced repetition applied to multiple choice questions.

What should you do with the questions you got wrong?

Go back through every wrong answer and sort the mistake into three buckets: something you never learned, two close ideas you are confusing, or plain carelessness. The first two are fixed by returning to that passage of the notes and retaking a targeted set. The third is fixed by reading the question more slowly. Without that sorting you retake the same quiz and repeat the same errors.

Then turn the failed items into flashcards, because those are exactly what spaced repetition should bring back over the following days. When the explanation still does not unlock a point, the AI tutor has your document in context and can explain it a different way.

Quiz, study sheet or flashcards: which one and when?

The three formats belong to different moments. A study sheet structures and condenses a chapter you are meeting for the first time or have forgotten. A quiz checks what you actually know and exposes the gaps. Flashcards keep discrete items such as definitions, dates and formulas alive over weeks. Study sheet, then quiz, then flashcards covers a chapter from the first lecture to the exam.

On Study-Genie all three come out of the same uploaded document, so they follow your course rather than a generic syllabus. The free plan gives 5 study sheets or quizzes per month, 10 flashcards and 150 messages with the AI tutor, with no card required. Premium at €14.99 per 28-day cycle and Ultimate at €19.99 open a weekly budget you split freely between sheets, quizzes, flashcards, scans and chat, and an annual commitment takes 15 percent off.
