How a quick online quiz fits into studying

A quick online quiz is most useful when you have a lecture PDF and only twenty minutes before the exam. Instead of rereading slides, you turn the material into questions and find out which ideas you can already recall.

Works with PDFs, PPTX slides, DOCX files, plain notes and photos of pages
Multiple choice, true/false and short-answer questions with explanations
Study in the browser on the free plan, with exports on paid plans
Pro adds QTI 2.1 and Moodle XML export for course platforms

Example digestive system quiz questions

Which organ produces bile that helps digest fats?The liver produces bile, which is stored in the gallbladder and emulsifies fats so lipase can break them down.

True or false: most nutrient absorption happens in the large intestine.False. Most absorption occurs in the small intestine, whose folded lining and villi greatly increase surface area.

Where does chemical digestion of proteins begin?In the stomach, where pepsin breaks proteins into smaller peptides in the acidic environment.

Which pancreatic enzyme digests starch?Pancreatic amylase, because it breaks starch into smaller sugars such as maltose in the small intestine.

Why does the esophagus rely on peristalsis?Peristalsis is wave-like muscle contraction that moves food down to the stomach, even when the body is not upright.

Questions from your own material

Upload PDFs, PPTX slides, DOCX files, notes or photos of pages. Text recognition reads images, so you can quiz yourself on a textbook page you photographed.

Three question types with explanations

Each quiz mixes multiple choice, true/false and short answer. Every question includes an explanation so a wrong answer teaches you something.

Export when you need it

Free plans study in the browser. Paid plans export to PDF, DOCX and Anki, and Pro adds QTI 2.1 and Moodle XML for course platforms.

How it works

Upload your material

Add a PDF, slides, DOCX, text notes or a photo of a page. No credit card is needed to start.

Choose question types

Pick multiple choice, true/false, short answer or a mix, then generate the quiz.

Take the quiz

Answer in the browser, read the explanations, and retake the questions you missed.

Short quizzes work well because they force active recall, and the explanations show why each answer is right or wrong. Mixing true/false items with short-answer prompts catches the gaps that multiple-choice guessing can hide.

DeckOwl builds the questions from your own files, so the quiz matches your course rather than a generic set. Free accounts get 3 generations per month, and paid plans remove that limit.

Frequently asked questions

How many questions should a quiz on the digestive system include?

Ten to fifteen questions cover the main organs and their functions in one sitting. Shorter quizzes of five questions work well for daily review.

What is a good way to study the order of digestion?

Quiz yourself on the path food takes from mouth to anus, then repeat the questions the next day. Short-answer items that ask you to name the next organ force better recall than recognizing the answer.

Is there a free plan, and can I export quizzes?

The free plan includes 3 generations per month and lets you study in the browser. Exports are a paid feature, starting with PDF, DOCX and Anki on Plus.

Can I export a quiz to Moodle?

Yes, Moodle XML export is included on the Pro plan at $14.99 per month. Plus at $39 per year or $7.99 per month covers PDF, DOCX, Anki and CSV export.
