Building the bank comes before the randomizing

If you want a Google Forms quiz that pulls random questions from a bank, the slow part is usually writing enough good questions to fill the bank in the first place. DeckOwl handles that step by generating multiple-choice, true/false, and short-answer questions from the notes or readings you already have.

Start from your own lecture slides, notes, or textbook chapters instead of generic sets.
Mix multiple-choice, true/false, and short-answer questions to test recall and understanding.
Read the explanation for every missed question before moving on.
Upgrade to Plus for PDF, DOCX, Anki, and CSV exports when you need your bank outside the browser.

Questions from your own material

Upload a lecture PDF, slide deck, or set of notes and get questions that match what you actually need to know.

Explanations for every answer

The free plan lets you study generated questions right in the browser, with three generations each month.

How it works

Upload your source

Add a PDF, DOCX, PPTX, text file, or image of a page. Photos are read with text recognition.

Choose question types

Pick multiple-choice, true/false, or short-answer questions to build the bank you want to draw from.

Quiz yourself

Practice with the questions and explanations, then come back to the weak spots as you study.

Each question includes an explanation, which matters more than the score when you are learning new material. Read the explanation after every miss, then return to the questions you got wrong until they stop tripping you up.

Frequently asked questions

How many questions should a question bank hold for a unit test?

There is no fixed number. Aim for enough questions that you can run several practice rounds without seeing the same ones in the same order every time.

How do I write good wrong answers for multiple-choice questions?

Make each wrong option a plausible mistake, such as a related term or a common misconception. Explanations that say why each distractor is wrong help more than a bare correct answer.

Can DeckOwl put questions straight into Google Forms?

DeckOwl does not list a Google Forms export. Plus includes PDF, DOCX, Anki, and CSV exports, and Pro adds QTI 2.1 and Moodle XML exports for learning systems.

Is DeckOwl free to try?

Yes. The free plan includes three generations per month and no credit card is needed to start. Students get 40% off with a school email.
