Turn a PDF into practice tests, checked against your material

    Upload a PDF and QuerySpark writes practice tests from what is actually in it, so you can rehearse the real exam on exactly what your course covers. PDF files up to 100 MB and 120 pages.

    Example

    Practice test from Cell Biology, Chapter 7

    A sample of what you get from a PDF on biology. Yours is written from your own file.

    1. Question 1 · Multiple choice

      Where in the cell does glycolysis take place?

      • Mitochondrial matrix
      • Cytoplasm
      • Inner mitochondrial membrane
      • Nucleus

      Glycolysis needs no organelle. It splits glucose into two pyruvate in the cytoplasm before anything enters the mitochondria.

    2. Question 2 · Multiple choice

      Cyanide stops ATP production in aerobic cells. Which step does it block?

      • Glycolysis
      • Pyruvate oxidation
      • Complex IV of the electron transport chain
      • The Krebs cycle

      Cyanide binds complex IV, so electrons cannot reach oxygen and the proton gradient that drives ATP synthase collapses.

    3. Question 3 · Short answer

      Why can muscle cells keep running glycolysis without oxygen, and what is the cost?

      Model answer: Lactic acid fermentation regenerates NAD+, so glycolysis continues, but it yields only 2 ATP per glucose instead of about 30.

    How we read PDFs

    We split long PDFs into page batches and read them with Google Document AI, which keeps headings, paragraphs and tables in reading order. Scanned pages are run through OCR automatically, and every item keeps a page reference so you can check the passage it came from.

    Get the best results

    • Trim to the chapters your exam covers.
    • Keep the figure captions. Many good questions come from them.
    • If your lecturer posts slides as PDF, upload those too: they show what was emphasized.

    What your practice tests include

    • A timed, exam-style test mixing question types
    • A score at the end, with every question you missed explained
    • Questions pitched at the level you choose, from high school to professional
    • The source passage behind every answer, so you can check it yourself

    How you study them

    Take it under exam conditions, then review your misses. Questions you got wrong go into your review queue so they come back before the real exam.

    Best for: mock exams, measuring readiness, teachers building assessments.

    Things that trip people up with PDFs

    • Scanned textbooks with skewed pages can drop a few words. OCR handles most of it, but a clean scan gives cleaner questions.
    • Two-column journal layouts sometimes interleave columns in cheaper tools. We keep layout order, so questions stay coherent.
    • Huge PDFs dilute focus. Upload the chapters on your exam rather than the whole 600-page book.

    Questions about pdf to practice test

    Does it work with scanned PDFs?+

    Yes. Scanned pages are detected and run through OCR before questions are written. Clean, straight scans give the best results.

    How long can the PDF be?+

    Up to 100 MB and 120 pages per upload. For a long textbook, upload the chapters your exam covers so every question is relevant.

    Can teachers assign the test to a class?+

    Yes. Create a class, share the join code, and assign the set. You see each student's progress on every assignment.

    Is the pdf to practice test converter free?+

    Yes. You can try it free with a 3-day Pro trial and no credit card, then keep using the free plan every month.
