Why build your own quiz instead of looking for a key

Canvas quiz answers are kept by your instructor, so no tool can pull them from a course, and copying a graded answer key would not teach you the material. What DeckOwl does is turn your own lecture slides, PDFs or notes into a fresh practice quiz on the same topics. Every question includes an explanation, which is the part most students skip when they check a key.

Practice questions are written from your own material, so they cover what your course actually taught.
Each answer includes an explanation, which helps you fix the reasoning behind a wrong choice.
Free plan: 3 generations per month with studying in the browser.
Plus and Pro add unlimited generations, and paid plans include PDF and DOCX export.

Example intro biology practice questions with answers

Which organelle is the main site of ATP production in eukaryotic cells?The mitochondrion. It carries out cellular respiration, which produces most of the cell's ATP.

True or false: Plant cell walls are made mainly of cellulose.True. Cellulose fibers form the rigid wall that gives plant cells structural support.

What region holds the DNA in a prokaryotic cell that has no nucleus?The nucleoid. It is a DNA-containing area in the cytoplasm that is not enclosed by a membrane.

Why does the phospholipid bilayer control what enters a cell?Its hydrophobic interior blocks most polar molecules, so transport proteins regulate what crosses. This is why the membrane is selectively permeable.

In osmosis, which way does water move across a membrane?Toward the side with the higher solute concentration. Water moves from low solute concentration to high solute concentration until the two sides balance.

Generate the full set

Built from your material

Upload PDFs, DOCX files, PPTX slides, plain-text notes or photos of pages, and get questions based on what you actually studied.

Explanations for every answer

Each question comes with a short reason for the correct answer, so you learn why an option is wrong instead of just memorizing a letter.

Question types that match your course

Choose multiple choice, true/false or open questions to practice recognition and recall in the format your exam uses.

How it works

Upload your notes

Add a lecture PDF, slide deck or photo of a textbook page. No credit card is needed to start.

Generate the quiz

DeckOwl writes questions with answers and explanations from the content you uploaded.

Practice and review

Take the quiz in your browser, then review missed questions until you can answer them without looking.

Self-testing works best when the questions are new to you. Generate a quiz after each lecture, miss a few on purpose, and read the explanations before you rewatch the lecture. Spaced review of the questions you got wrong builds recall that lasts until the exam.

Frequently asked questions

How many practice questions should I make for an intro biology unit?

Twenty to thirty questions covering one unit is a good first pass for most students. Add more questions on the topics you keep missing, and mix multiple choice with short answer so you practice recall, not just recognition.

How do I study cell structure effectively?

Quiz yourself on each organelle's function before you reread the diagrams, then check your answers against your textbook. Reviewing the questions you missed on a spaced schedule works better than rereading the whole chapter.

Can I export a quiz to use in Canvas?

QTI 2.1 and Moodle XML export are available on the Pro plan, and PDF, DOCX and Anki export are included on Plus. Export is a paid feature, so the free plan lets you study in the browser only.

Is the free plan enough to try DeckOwl?

The free plan includes 3 generations per month and browser study, and no credit card is needed to start. Students get 40% off paid plans with a school email.
