Why teachers and students use an online quiz maker

Teachers and students often need an online quiz maker for school that starts from existing material instead of a blank page. Writing ten good questions with clear wrong answers takes time that most people would rather spend on lesson planning or revision.

  • Works from PDFs, slides, DOCX files, notes and photos of pages
  • Multiple-choice, true/false and short answer question types
  • Explanations on every question so wrong answers become lessons
  • Free plan includes 3 generations per month with browser study
Example middle school biology quiz questions
Which organelle is the site of photosynthesis in plant cells?Chloroplast. It contains chlorophyll, which captures light energy and uses it to make sugar.
Which organelle is known as the powerhouse of the cell?Mitochondria. They release energy from glucose through cellular respiration.
True or false: animal cells have a rigid cell wall.False. Cell walls made of cellulose are found in plant cells, not in animal cells.
What genetic instructions does the nucleus contain?DNA. It controls which proteins the cell makes.
Why does a plant cell not burst when placed in pure water?Its cell wall resists swelling, so pressure from the water keeps the cell firm.

Questions from your material

Multiple-choice, true/false and short answer questions are generated from the text in your own files, not from generic topics.

Explanations on every answer

Each question includes a short explanation of why the correct answer is right, so students learn from misses instead of just seeing a score.

Export when you need it

Plus exports to PDF and DOCX. Pro adds QTI 2.1 and Moodle XML for classes that run on a learning management system.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, plain text file or a photo of a page. Photos are read with text recognition.

Choose the question types

Pick multiple-choice, true/false or short answer, then set how many questions you want for the quiz.

Share or export the quiz

Students take the quiz in the browser. Paid plans can export the quiz for printing or for your class system.

A quiz built from your own notes checks the material your class actually covered. Because each question comes with an explanation, a student who misses one can see the reason right away and try again later.

DeckOwl generates the first draft from your files, so you can edit the wording, remove anything off-topic and keep the questions that match your lesson.

Frequently asked questions

How many questions should a classroom quiz have?

Most classroom quizzes work well with 10 to 20 questions, which usually takes students 15 to 30 minutes. Mixing multiple choice with a few short answer items checks recall more deeply.

How should students study with a quiz?

Students should answer without notes first, then read the explanation for every missed question. Retaking the missed questions a day or two later helps the answers stick.

Can I export the quiz to my learning management system?

Yes, but export is a paid feature. Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML export.

Do I need a credit card to start?

No. The free plan gives you 3 generations per month with browser study, and students get 40% off with a school email.
