Gemini Quiz Generator: Google Gemini Quiz Maker Prompts to Make a Quiz From a PDF

The short answer

Gemini will write quiz questions from an attached document, and Google publishes the document ceiling clearly: 50 MB and 1,000 pages, with each page costing about 258 tokens. That is generous, and it is the main reason people reach for Gemini on long source material. The gap is on the output side. You get questions in a chat thread, not a numbered student copy, not a separate answer key, and not something a class can sit and be scored on. Upload the same file here and those three artifacts come back finished.

Last updated July 2026. Limits verified against Google's Gemini API document processing documentation.

What Gemini actually accepts, per Google's own documentation

These are the numbers Google publishes for document processing. They matter before you start prompting, because a file past either ceiling is rejected outright rather than partially read.

Constraint	Documented limit	What it means for a quiz
Maximum file size	50 MB per document	Text heavy chapters clear this easily. Image heavy scans of a full textbook usually do not.
Maximum pages	1,000 pages per document	Almost no course reading hits this. Compliance manuals and standards documents sometimes do.
Token cost per page	About 258 tokens	A 300 page manual is roughly 77,000 tokens of source before your prompt. Long context is where coverage quietly degrades.
Page rescaling	Pages scaled to a maximum of 3072 by 3072 pixels	Small print in a low quality scan loses detail during that rescale, which shows up as wrong numbers in questions.
Over the limit	Rejected, not truncated	You find out immediately rather than getting a quiz built from half a document.

Gemini quiz maker prompts that produce something usable

Attach the file first, then paste. Every prompt here names the source, the count, the format, the level, and the output layout, which is the combination that stops the model defaulting to definition recall.

Even coverage of a long document

Write 25 multiple choice questions from the attached PDF, distributed evenly across every chapter, four options each with one correct answer. After the questions, list the answer key and name the chapter each item came from.

Questions above recall level

Write 12 questions at the apply and analyze levels. Each stem must present a short scenario, and no question may be answered by matching a phrase from the document. Explain in one line why each correct answer is correct.

Distractors worth having

Rewrite the wrong answers so each one reflects a specific misunderstanding a learner might hold. Keep all options roughly the same length, remove any option that is obviously absurd, and never use all of the above.

A coverage audit before you trust it

List every major section of the attached document, then state how many of the questions you wrote came from each one. This one prompt exposes the gaps faster than reading the quiz does.

A fuller walkthrough lives in how to make a quiz with Gemini.

Gemini versus a purpose built quiz generator

Gemini is strong at reading a document and reasoning about it. The split shows up the moment the quiz has to leave the chat window as a real artifact.

Job	Google Gemini	PDFQuiz
Reading a large document	Up to 50 MB and 1,000 pages, published clearly	One file per upload, generous for chapters and decks
Writing the questions	Good, given a specific prompt	Good, with format and count as controls instead of prose
Separate answer key	In the same reply unless you ask for it separately	Student copy and key download as two files
Printable test formatting	Manual cleanup after copying out	PDF or Word, numbered, with answer space
A quiz others take and get scored on	No	Yes, shareable and graded
Source already in Google Drive	Native advantage, it is the same account	Download then upload, one extra step
Getting into Google Forms	Still manual, Forms has no bulk text import	Same constraint, documented in PDF to Google Form
Reusing items next term	Search your chat history	Saved as a question bank

How to get the quiz without prompting for it

Step 1

Upload the source

Chapter, manual, handout, or deck. If it lives in Drive, download it once and upload it here.

Step 2

Set count and format

Multiple choice, true or false, short answer, or a mix, with the number of items you want.

Step 3

Review against the source

Check the distractors and any item with a number or a date in it. That is where every model is weakest.

Step 4

Share or print

Send a scored link, or download the student copy and the answer key separately.

Who runs into the output gap

Google Workspace schools

Source material is already in Drive, so Gemini is the obvious first stop. The wall is the printable test and the key, every week.

Corporate training teams

A scored, recorded result is the deliverable. Chat output is not evidence, which is the whole point of a compliance knowledge check.

Instructional designers

Course length material makes coverage the real risk, and coverage is what long context handles least predictably.

Students revising

Conversational quizzing genuinely works for self testing. For a stable set to repeat, see notes to quiz.

Questions people ask about making quizzes with Gemini

Can Gemini make a quiz?

Yes. Attach the source file in the Gemini app, ask for a set number of questions in a named format, and it writes them. Gemini can also present questions one at a time so you answer as you go. What it does not return is a numbered student copy and a separate answer key as two files you can print and hand out.

How do you generate a quiz in Gemini from a PDF?

Open the Gemini app, use the attach control to add the PDF, then prompt for the question count, format, difficulty, and where the answer key should go. Keep the file under Google's documented limits of 50 MB and 1,000 pages. Ask it to name the section each question came from so you can check coverage.

What is the best Gemini prompt for making a quiz?

Name five things in one prompt: the attached source, the number of questions, the exact format, the cognitive level, and the output layout including a separate answer key. For example, write 20 multiple choice questions from the attached PDF, four options each, evenly spread across all sections, then list the key at the end with the section for each item.

How large a PDF can Gemini read?

Google's developer documentation puts the ceiling at 50 MB and 1,000 pages per document, with each page counted as roughly 258 tokens. Files past either limit are rejected rather than truncated. A 1,000 page manual is inside the limit on paper, but question coverage across that much material is a separate problem from whether the file is accepted.

Can Gemini read a scanned PDF?

It processes pages visually, so a clean scan usually works and a skewed phone photo of a textbook often does not. Google's docs note that pages are rescaled during processing, which is why small print in a poor scan degrades. If the file has no text layer at all, check the questions carefully against the original. Our take on that case is on scanned PDF to quiz.

Is Gemini or ChatGPT better for making quizzes?

Neither wins outright. Gemini has published, generous document limits and sits next to Google Docs and Drive, which matters if your source material already lives there. ChatGPT is more flexible about output format on request. Both leave you with text in a chat window rather than a printable test with a matching answer key. The prompt side of ChatGPT is covered on the ChatGPT quiz generator page.

Can Gemini create a quiz in Google Forms?

Gemini can draft the questions, but Google Forms has no bulk import for a block of text, so each item still gets added by hand or through an add on script. For a class set of 25 questions that is the bulk of the work, and it is the step people underestimate.
