How to turn a textbook PDF into practice questions
Stop rereading the chapter. Turn any textbook PDF into practice questions by hand or with AI, and know which question types help you remember most.
Key takeaways
- Rereading a chapter builds familiarity, not memory, so turn the PDF into questions instead.
- Chunk the chapter into short sections and write questions from the headings, bold terms, and end-of-chapter problems.
- AI can generate a quiz from a PDF quickly, but scanned pages and diagrams need extra checking.
You've read the chapter twice and highlighted half of it. Then you open a practice test and draw a blank. This guide shows you how to turn a textbook PDF into practice questions, by hand or with AI, so your study time goes into remembering instead of rereading.
Why rereading a PDF feels productive but isn't
Rereading feels good because the words look familiar on the second pass. Your brain mistakes that familiarity for knowing the material.
A major review of ten study techniques rated rereading and highlighting as low utility. Practice testing and spaced practice were rated high utility (Dunlosky et al., 2013). The difference is effort. A question forces you to pull the answer out of memory, and that effort is what makes it stick.
So the goal is not to read the PDF more. It's to turn the PDF into something that tests you.
Chunk the chapter first
A 30-page chapter is too big to work with in one go. Break it up before you write a single question.
- Skim the whole chapter in five minutes. Read the headings, the summary, and the end-of-chapter questions. This gives you the map.
- Split it into sections of two to three pages. Most textbooks already do this with subheadings.
- Work through one chunk at a time. Read it once, carefully, then close it and write questions before moving on.
- Take a short break every two or three chunks. Long unbroken sessions make it harder to focus on the later sections.
Chunking also makes it easy to spread a chapter across several days, which matters for review later.
Turn headings and bold terms into questions
Textbook authors already marked what matters. Use their structure.
Headings become "what" and "why" questions. A heading like "Factors affecting enzyme activity" becomes "What factors affect enzyme activity?" and "Why does high temperature reduce enzyme activity?"
Bold terms become definition questions. Every bolded word is a likely exam term. Write "What is a competitive inhibitor?" not "Competitive inhibitor."
Figures become explain questions. For each graph or diagram, ask "What does this figure show, and why does the curve change shape here?"
End-of-chapter problems become cards. Write each problem on the front and your worked answer on the back. Redo them later without looking at the solution.
Chapter summaries become a final check. Turn each summary bullet into a question. If you can answer all of them, you've covered the core.
Which question types to use (MCQ, short answer, cloze)
Different question types test different things. A good set mixes them.
| Type | What it tests | Best for | Watch out for |
|---|---|---|---|
| Multiple choice | Telling the right answer from close options | Exams that use MCQ, fast self-checks | Easy to guess, can test recognition only |
| Short answer | Producing the answer from memory | Definitions, explanations, steps | Takes longer to check |
| Cloze (fill in the blank) | Exact recall of a key word or number | Formulas, terms, dates | Can be too narrow on its own |
| Worked problem | Applying a method to a new case | Math, physics, chemistry, economics | Needs a full solution to check against |
A meta-analysis of practice testing research found that taking practice tests improved learning compared with other ways of studying the same material, across many kinds of tests and settings (Adesope, Trevisan & Sundararajan, 2017). The practical takeaway: any reasonable question format beats rereading, so don't stall choosing one.
A practical mix: use multiple choice for a quick first pass, then short answer for anything you missed. That way you get speed early and deeper recall where you need it.
Using AI to generate a quiz from a PDF, and its limits
Writing 25 questions by hand for one chapter takes a while. AI tools can draft them in seconds from the PDF itself.
The manual way with a general chatbot
You can paste a section's text into a chatbot like ChatGPT and ask:
Write 10 practice questions from this text: 5 multiple choice and 5 short answer. Include answers, and quote the sentence each answer comes from.
Do one chunk at a time. Pasting a whole book at once tends to produce vague questions about the biggest themes only.
The BrainLift way
In BrainLift, you upload the PDF and it generates a quiz and a matching flashcard deck from the content. Take the quiz first. Then use "practice my mistakes" to turn the questions you got wrong into a flashcard deck for review. If you'd like to try it on your next chapter, BrainLift is free to start on iPhone, iPad, and the web.
The limits to know about
- Scanned PDFs. If your PDF is a photo of pages rather than real text, the tool has to read the image first. Blurry or skewed scans lead to misread words.
- Diagrams and graphs. AI works mostly from the text. Questions about a figure may miss what the figure actually shows.
- Equations. Complex math notation can get scrambled. Check every formula.
- Wrong or invented answers. AI can state things the chapter never said. Always check answers against the page they came from.
A quick way to check: pick five questions at random, find each answer in the PDF, and fix or delete anything that doesn't match. If more than one is wrong, check the whole set.
Building a review schedule for the whole book
Making questions is half the job. Answering them again over several weeks is the other half.
- Same day: Answer every question for the chunks you studied.
- Two days later: Answer them again. Mark the misses.
- One week later: Do the misses plus a sample of the rest.
- Each new chapter: Add a few questions from older chapters into your session. Mixing old and new keeps earlier material fresh.
- Before the exam: Do a full mixed quiz across all chapters, then drill only your misses.
For a deeper look at why spacing works, read active recall vs spaced repetition. If the exam is close and you're covering several courses, the finals week study plan shows how to fit it together.
Example: a 20-page chapter to 25 questions
Here's how a 20-page chapter on enzymes might break down.
Step 1: Chunk it. The chapter has six subheadings, so that's six chunks of about three pages each, plus the summary.
Step 2: Write questions per chunk.
- Chunk 1, enzyme structure: 4 questions (2 definitions, 1 explain, 1 cloze)
- Chunk 2, how enzymes lower activation energy: 4 questions (1 figure question, 3 short answer)
- Chunk 3, factors affecting activity: 5 questions (temperature, pH, concentration, plus 2 "why" questions)
- Chunk 4, inhibitors: 4 questions (competitive vs noncompetitive, with an example of each)
- Chunk 5, regulation: 3 questions
- Chunk 6, enzymes in medicine: 2 questions
- Summary and end-of-chapter problems: 3 questions
Step 3: Mix formats. About 10 multiple choice, 10 short answer, and 5 cloze.
Step 4: Check and schedule. Spot-check answers against the text, then set your first review for two days later.
That's 25 questions in total, and they cover the whole chapter. Answering them a few times over two weeks will do more than another full reread.

FAQ
What's the best way to study from a PDF textbook?
Skim the chapter, split it into short sections, and write questions for each section after reading it once. Then answer those questions again over several days instead of rereading the chapter.
Can AI make a quiz from a PDF accurately?
It can draft a useful quiz quickly, especially from text-based PDFs. Scanned pages, diagrams, and equations cause more errors, so check answers against the source page.
How many practice questions should I write per chapter?
About one question per page is a good starting point, so roughly 20 to 30 for a typical chapter. Dense chapters with lots of terms may need more.
Are multiple-choice questions enough to study with?
They're a good start, but mix in short-answer questions. Producing an answer from memory is harder than picking it from a list, and it shows more clearly what you really know.
What if my PDF is a scan?
Check that the text is sharp and straight. If an AI tool misreads it, write questions by hand for the hardest sections, or retype the key paragraphs before generating questions.
