How a custom quiz helps you study

If you want a quiz that tests the chapter you are actually reading instead of a generic question set, upload that chapter to DeckOwl. The quiz is written from your own text, so the questions match your lectures and textbook wording.

  • Quizzes are generated from the files you upload, not from a shared library.
  • Each question includes an explanation of the correct answer.
  • Multiple choice, true/false and short answer formats are available.
  • The free plan includes 3 generations per month, with quizzes taken in the browser.
Example intro biology quiz questions (no subject was named, so biology is used)
Which organelle produces most of a cell's ATP?Mitochondria. They carry out cellular respiration, which converts glucose and oxygen into ATP.
What is the function of the cell membrane?It is a selectively permeable barrier that controls what enters and leaves the cell.
True or false: plant cells have a cell wall made of cellulose.True. The rigid cellulose wall gives plant cells structure and protection.
Which molecule carries genetic instructions out of the nucleus?Messenger RNA (mRNA). It copies the code from DNA and carries it to the ribosomes.
In photosynthesis, which gas do plants take in?Carbon dioxide. It is fixed into sugar in the Calvin cycle, which uses energy from light.

Built from your files

Upload PDF, DOCX, PPTX, plain text or a photo of a page. Text is read from images, so handwritten-scan pages work too.

Three question types

Get multiple choice, true/false and short answer questions in one quiz, each with an explanation of the correct answer.

Study where you are

Take the quiz in your browser on the free plan. Paid plans add exports to PDF, DOCX, Anki and CSV.

How it works

Upload your material

Add the file or photos you are studying from. Lecture slides and textbook chapters both work.

Choose a quiz

Pick the question types you want and generate the quiz. Each generation counts toward your monthly limit on the free plan.

Answer and review

Take the quiz, read the explanation for every answer, and retry the questions you missed.

Short answer and true/false questions show you what you understand, while multiple choice questions with explanations show why the wrong options are wrong. Retaking only the questions you missed is a faster way to find gaps than rereading everything.

Students get 40% off with a school email, and no credit card is needed to start.

Frequently asked questions

How many quiz questions should I study at once?

A set of 10 to 20 questions is a good size for one sitting. Focus on one chapter or topic per quiz so the results point to specific gaps.

How do I study for a biology quiz on cell structure?

Take the quiz once without notes, then reread the explanations for every missed question. Retake the missed questions after a day or two to check that the answers have stuck.

Can I export my quiz?

Exports are a paid feature. Plus includes PDF, DOCX, Anki and CSV export, and Pro adds QTI 2.1 and Moodle XML export.

Do I need a credit card to try it?

No. You can start on the free plan without a credit card, which includes 3 generations per month and browser study.
