How to Make a Quiz with AI: ChatGPT, Gemini, and Quizizz (2026)

A good quiz takes most teachers 30 to 45 minutes to write — and then another evening to grade. Let AI do the two slow parts: ChatGPT or Gemini writes the questions, and Quizizz turns them into an interactive quiz that grades itself. The whole process takes under 30 minutes, and your students get their results the moment they finish.

Each tool has one job here. ChatGPT or Gemini writes the questions. Quizizz delivers them, times them, and marks them. Do not ask one tool to do the other’s job.

What you need before you start (5 minutes)

Have these four things ready:

Topic and grade — for example, “Grade 6 science, the Solar System.”
One learning objective — what the quiz should test. Not “the Solar System” but “name the eight planets in order and give one key fact about each.”
Question count and mix — a good default for a 15-minute quiz: 10 questions — 6 multiple choice, 2 true/false, 2 short answer.
A free Quizizz teacher account — the free plan covers everything in this guide, including auto-grading and reports.

If you skip the question mix, you will get ten multiple-choice questions of the same difficulty — and a quiz that tells you nothing about what your students actually know.

Step 1: Generate the questions with ChatGPT or Gemini (10 minutes)

Copy and adapt this prompt. Fill in the brackets:

Act as an experienced [grade] teacher. Create a [number]-question quiz on [topic] for [grade] students. Include [mix, e.g. 6 multiple choice, 2 true/false, 2 short answer]. The learning objective is: [one sentence]. Each multiple-choice question must have exactly one correct answer and three plausible wrong answers. Mark the correct answer clearly. Include an answer key at the end.

Which tool should you use? Both work. Use Gemini if your source material is already in Google Docs or Google Drive — it can read those files directly and write questions from them. Use ChatGPT if you want tight control over the format, or if you already use it for your lesson plans.

Two follow-ups that fix most problems:

Harder questions: “Make questions 5 to 8 harder, for students who finished early.”
Fix a bad question: “Rewrite question 2 — it has two correct answers.”

Each follow-up takes seconds. Do not accept a question you would not be happy to defend in front of a parent.

Step 2: Check the questions like a teacher (5 minutes)

Read the questions once before you touch Quizizz:

Is there exactly one correct answer? AI multiple-choice questions often have two answers that could both be right. Fix those first — they are the questions students will argue about.
Are the answers correct? Check every answer key entry yourself. AI invents facts confidently, especially in science and history.
Are the wrong answers plausible? A wrong answer that no student would ever pick tells you nothing. Good wrong answers are the mistakes students actually make.
Is the level right? If the hardest question is too easy, replace it. Do not add three more easy ones.

Fix problems in the chat with a specific instruction: “Question 4 has two correct answers. Rewrite it with only one.” That works far better than “make it better.”

Step 3: Build the quiz in Quizizz (10 minutes)

In Quizizz, create a new quiz and give it a clear name — the topic and the class, for example “Solar System — Grade 6”.
Add the questions one by one. For each multiple-choice question, paste the question, add the four options, and mark the correct one. Set a time limit per question — 30 seconds for quick recall, 60 seconds for questions that need thinking.
Turn on “shuffle answer options” if you want each student to see the answers in a different order. It takes one click and makes copying much harder.
Add a short instruction at the top of the quiz, for example “Answer all 10 questions. You have 30 seconds per question.” Students do better when they know the rules before question 1.
Check the quiz once with the preview, as a student would see it. Look for questions cut off on small screens, and for answer options that are too long to read in the time limit.

Quizizz also has its own AI question generator. It works, but the questions it writes from a bare topic are generic — the questions you generate with your own prompt, from your own objective, will fit your class better.

Step 4: Assign it and read the results (5 minutes)

Assign the quiz as homework or run it live in class. Students join with a code or a link — no accounts needed on their side.
While students play, watch the live results. You will see immediately which questions most students get wrong.
After the quiz, open the report. Look for two things: the questions with the lowest scores (that is tomorrow’s revision topic) and the students who finished far below the class (that is who needs help first).
Save the quiz. Next time you teach the topic, you only change the questions that did not work — the rest is already done.

The report is the real reason to use Quizizz instead of a paper quiz. A paper quiz tells you a score. A Quizizz report tells you exactly which question to reteach.

A complete example

Here is the prompt filled in, so you can see what “specific” looks like:

Act as an experienced Grade 6 science teacher. Create a 10-question quiz on the Solar System for Grade 6 students. Include 6 multiple choice, 2 true/false, and 2 short answer questions. The learning objective is: students can name the eight planets in order and give one key fact about each. Each multiple-choice question must have exactly one correct answer and three plausible wrong answers. Mark the correct answer clearly. Include an answer key at the end.

In Quizizz, that becomes a 10-question quiz called “Solar System — Grade 6”: 30 seconds per quick-recall question, 60 seconds for the short answers, answer options shuffled, and a report that shows which planet facts the class still mixes up. The same structure works for any subject — change the topic and the mix, and the steps stay the same.

Common mistakes to avoid

Writing 20 questions for a 15-minute quiz. Students rush the last five and you learn nothing from them. Ten good questions beat twenty rushed ones.
All multiple choice, all the same difficulty. Mix the types and the levels, or the quiz cannot tell a strong student from a lucky one.
Ambiguous wording. If a question can be read two ways, students will read it the wrong way. Read each question once as a 12-year-old would.
No time limit per question. Without one, a quiz drags on and fast finishers get bored while slow starters are still on question 3.
Trusting the answer key without checking it. One wrong answer in the key means every student who knew the right answer gets marked wrong — and they will tell you about it.

FAQ

Is Quizizz free for teachers?

Yes. The free plan covers creating quizzes, assigning them, auto-grading, and reports. Paid plans add extras, but nothing in this guide needs them.

ChatGPT or Gemini — which is better for quiz questions?

Both are fine. Use Gemini when your source material is in Google Docs or Drive, because it can read those files directly. Use ChatGPT when you want strict control over the format, or when you already use it for your other teaching materials.

Can students cheat with AI during the quiz?

They can try, like with any quiz. Shuffle the questions and the answer options, set a time limit per question, and use the quiz as a low-stakes check for learning rather than a high-stakes test. The goal is to find out what to reteach, not to catch anyone.

Can I print the quiz instead of running it online?

Yes. Quizizz lets you print a quiz as a worksheet, with or without the answer key. It is a good backup for classrooms with unreliable internet — or for a substitute teacher.
