Turn your math notes into a practice quiz in minutes
Upload a PDF, slide deck, text file or photo of a page. DeckOwl writes multiple-choice, true/false and short-answer questions from your own material, each with an explanation.
Why build your own math quiz
Students who need Sapphire math quizzes often have the answers in a course packet, lecture slides or handwritten notes rather than a ready-made test. A quiz written from your own material checks the exact methods and definitions your instructor used.
- Works with PDFs, slides, notes and photos of pages
- Multiple-choice, true/false and short-answer formats
- Explanations on every question so you learn from misses
- No credit card needed to start
Questions from your material
The quiz is built from the pages you upload, so it matches what your class actually covered.
Explanations for every answer
Each question comes with a short explanation, so a wrong answer teaches you the step you missed.
Three question formats
Mix multiple choice, true/false and open short-answer questions to test recall and application.
How it works
Upload your material
Add a PDF, DOCX, PPTX, text file or a photo of printed pages.
Choose a question type
Pick multiple choice, true/false or short answer, or combine them in one quiz.
Take the quiz and review
Answer in the browser, read the explanations, and retry the questions you missed.
A practice quiz works best when you attempt each question before reading the answer. Open-ended questions show whether you can set up a problem, while multiple choice and true/false questions catch common mistakes quickly.
Start with the free plan to try a quiz from one chapter. Upgrade when you want to export the questions for review with a study group or import them into another tool.

Frequently asked questions
How do I study for a math quiz effectively?
Attempt each practice question before checking the answer, then rewrite the steps for any question you got wrong. Repeat the missed questions a day or two later to see if the method has stuck.
How many practice questions should I work through before a math test?
There is no fixed number. Keep practicing until you can solve a mix of question types from each topic without looking at worked examples.
Can I export my math quiz?
The free plan lets you study quizzes in the browser without exports. Plus ($39/year or $7.99/month) adds PDF and DOCX export, and Pro ($14.99/month) adds QTI 2.1 and Moodle XML export.
Do I need a credit card to start?
No. You can start on the free plan without a credit card, and students get 40% off a paid plan with a school email.
