How to make your own quiz from study material

Writing a quiz from scratch takes time, and most of it goes into rereading the chapter to find testable facts. With DeckOwl you can make your own quiz from material you already have, whether that is a lecture deck, a DOCX handout or a photo of a textbook page.

  • Multiple-choice, true/false and short answer question types
  • Explanations for every answer, right or wrong
  • Works from PDF, DOCX, PPTX, text notes and photos of pages
  • Free plan includes 3 generations per month with no credit card needed
Example biology quiz questions
Which organelle produces most of a cell's ATP through aerobic respiration?The mitochondrion. Most ATP is made by oxidative phosphorylation across its inner membrane.
True or false: mitosis produces four genetically distinct daughter cells.False. Mitosis produces two genetically identical daughter cells, while meiosis produces four distinct gametes.
In osmosis, which direction does water move across a membrane?Toward the side with higher solute concentration, because water moves down its own concentration gradient.
What is the job of helicase during DNA replication?It unwinds the double helix by breaking hydrogen bonds between base pairs, creating the replication fork.
Why does a red blood cell burst when placed in pure water?Water enters by osmosis because the cytoplasm is more concentrated than the surrounding water, and the membrane eventually ruptures.

Questions from your material

Generate questions from your own PDFs, slides, notes or photos of pages instead of generic filler.

Explanations included

Each answer comes with a sentence explaining why it is right or wrong, so misses teach you something.

Export on paid plans

Plus exports to PDF, DOCX, Anki and CSV. Pro adds QTI 2.1 and Moodle XML for learning systems.

How it works

Pick multiple-choice, true/false or short answer questions for your quiz.

Study and generate again

Take the quiz in your browser, read the explanations, and create fresh questions when you need them.

Each question comes with an explanation, so a wrong answer teaches you something instead of just marking you down. Quizzes run in the browser on every plan, and paid plans export to PDF or DOCX if you want a printed copy for class.

Frequently asked questions

How many quiz questions should I write for a single chapter?

Aim to cover each major heading with a few questions rather than fixing a total. Start with key terms and definitions, then add questions that ask you to apply the idea.

How do I study effectively once I have made a quiz?

Answer without notes first, then read the explanation for every miss before retrying. Come back to the questions you got wrong after a day or two rather than rereading the whole chapter.

Can I export my quiz to use in class?

Yes, the Plus plan exports to PDF and DOCX, and Pro adds QTI 2.1 and Moodle XML. The free plan lets you study in the browser without exports.

Do I need a credit card to try DeckOwl?

No, you can start on the free plan without a credit card, which includes 3 generations per month. Students with a school email get 40% off paid plans.
