Why an online quiz maker works better with your own material

Teachers and students who need practice questions often end up writing them by hand. A online quiz maker built on your own material skips that step: upload a lecture deck, textbook chapter or set of notes, and DeckOwl writes questions that match what you actually covered.

  • Questions come from your own lectures and readings, not a generic question bank.
  • Every question includes an explanation, so wrong answers still teach something.
  • The free plan includes 3 generations per month with browser study and no exports.
  • Plus adds unlimited generations and PDF or DOCX export; Pro adds QTI 2.1 and Moodle XML export.
Example immune system quiz questions
Which white blood cells mature into plasma cells that secrete antibodies?B cells. They are activated by antigens and differentiate into plasma cells that produce large amounts of antibody.
Which type of immunity does a vaccine mainly train?Adaptive immunity. Vaccines prime memory B and T cells so the body responds faster on later exposure without causing the disease.
True or false: red blood cells are the main cells that fight infection.False. White blood cells (leukocytes) fight infection, while red blood cells carry oxygen.
Where do T cells mature and learn to tell self from non-self?The thymus. T cells are trained there so that they attack foreign antigens rather than the body's own tissues.
Which phagocytes engulf and digest bacteria and cell debris?Macrophages and neutrophils. They are innate immune cells that ingest pathogens through phagocytosis.

Three question types

Multiple-choice, true/false and short-answer questions are generated from your material.

An explanation for every answer

Each question explains why the correct answer is right, so wrong answers still teach you something.

Browser study and paid exports

Take quizzes free in the browser. PDF and DOCX export come with Plus, and QTI 2.1 and Moodle XML export come with Pro.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain notes or a photo of a page.

Pick your question types

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

Take the quiz and review

Check your answers, read the explanations, and export the quiz if you are on a paid plan.

Because the questions come from your files, the quiz stays focused on your course instead of a generic question bank. Each item includes an explanation, so a missed answer becomes a quick review rather than a dead end.

The free plan includes 3 generations per month and browser study. Plus, at $99.90/year or $9.99/month, adds unlimited generations and PDF or DOCX export, and Pro at $14.99/month adds QTI 2.1 and Moodle XML export for learning management systems.

Frequently asked questions

How many quiz questions should I write for the immune system?

Start with 10 to 15 questions for one chapter so you can cover innate and adaptive immunity without overloading a single session. Add more questions for each new topic, such as antibodies, T cells and vaccines.

How should I study immune system quiz questions?

Answer each question before reading the explanation, and keep a list of the ones you miss. Retry the missed questions after a day or two so the material moves into long-term memory.

Can I export my quiz?

Exports are paid features: PDF and DOCX export come with Plus, and QTI 2.1 and Moodle XML export come with Pro. The free plan lets you take quizzes in the browser.

Do I need a credit card to start?

No. You can start on the free plan with 3 generations per month and no credit card. Students can also get 40% off with a school email.
