Turn your math notes into a practice test with answers
Upload a PDF, slides, DOCX, or photos of your textbook pages. DeckOwl writes multiple-choice, true/false, and open questions, each with an answer and an explanation.
Why a custom math test beats a generic printable
Printable math worksheets are written for an average class, so their topics and difficulty rarely match your homework or exam. A free math practice test with answers built from your own notes closes that gap by drawing questions straight from the pages you are studying.
- Questions match the chapter you are on, not a generic syllabus.
- Each answer includes a one-sentence explanation you can review.
- The free plan includes 3 generations per month and study in the browser.
- PDF, DOCX, Anki, and CSV exports are available on the Plus plan.
Answers with explanations
Every question comes with a correct answer and a short explanation, so you learn why a method works, not just the final result.
Three question types
Choose multiple choice, true/false, or open questions, depending on how your course tests you.
Built from your material
Questions come from the pages you upload, so the practice follows the chapter you are actually studying.
How it works
Upload your material
Add a PDF, DOCX, PPTX, plain-text notes, or a photo of a worked problem set.
Pick the question type
Select multiple choice, true/false, or short answer, then generate the test.
Work through it and repeat
Take the test in your browser, check each explanation, then generate a new set on the pages you missed.
Upload a PDF, slide deck, or photo of worked problems, and DeckOwl generates questions with explanations for each answer. Check your work, read why the correct option holds, and try a fresh set until the steps feel routine.

Frequently asked questions
How many practice problems should I work through before a math test?
Aim to cover every method in the chapter at least twice, with extra attention on the ones you miss. Retrying problems a day or two later helps them stick better than one long cram session.
Should I check my answers right away or try the whole set first?
Try the full set without notes first, then check answers and read each explanation. Mark the questions you guessed, since a correct guess still means that method needs review.
Can I export the practice test to PDF?
PDF, DOCX, Anki, and CSV exports are on the Plus plan, which costs $39/year or $7.99/month. The free plan lets you study the test in your browser.
Do I need a credit card to start?
No. You can start on the free plan with 3 generations per month and no credit card, and students get 40% off with a school email.
