Find out what you should study with a free practice quiz
Upload your class notes, slides or PDFs and get practice questions with explanations. Your missed answers show which topics need review first.
Why a quiz beats guessing what to review
When an exam is a week away and every chapter feels urgent, a free quiz that shows what you should study can save hours of guessing. Quizzes reveal gaps faster than rereading, because a wrong answer points to the exact concept that is still weak.
- Start with the topics where you missed the most questions.
- Retake missed questions after a day or two rather than all at once.
- Read the explanation even when you answered correctly to confirm your reasoning.
- Generate a new quiz from the next chapter once your weak topics improve.
Questions from your material
Multiple-choice, true/false and short-answer questions are generated from the notes you upload, so the quiz matches your course.
Explanations for every answer
Each question includes an explanation, so a wrong answer teaches you the concept instead of just marking it incorrect.
Study in the browser for free
The free plan includes 3 generations per month and studying in the browser, with no credit card needed to start.
How it works
Upload your notes
Add a PDF, DOCX, PPTX, plain-text notes or photos of pages. Text in images is read with text recognition.
Take the quiz
Answer the generated multiple-choice, true/false or short-answer questions and check the explanations as you go.
Study the weak spots
Review the topics where you missed questions first, then retake the quiz to see what has improved.
Free quizzes that already exist online rarely match your course, so a generated one works better. DeckOwl builds the quiz from your own PDFs, slides, notes or photos, then gives you multiple-choice, true/false and short-answer questions with explanations for each one.
The free plan lets you run 3 generations per month and study right in the browser. Plus adds unlimited generations and PDF or DOCX export, and Pro adds a stronger AI model and bulk upload.

Frequently asked questions
How do I know which topics I should study first?
Take a quiz on your full set of notes, then sort the missed questions by topic. Start with the topics that have the most misses, since they have the most room to improve.
How many practice questions should I do before an exam?
Aim for enough questions to cover each chapter at least once, then retry the ones you missed. Spacing out those retries usually works better than one long session.
Is the free plan really free?
Yes, the free plan includes 3 generations per month and studying in the browser, with no credit card needed. Exports require a paid plan.
Can I export my quiz?
PDF and DOCX export come with Plus at $39/year or $7.99/month, and QTI 2.1 and Moodle XML export come with Pro at $14.99/month. Students get 40% off with a school email.
