Practice math with a quiz built from your own notes
Upload your algebra notes, geometry slides or worked problem sets and get multiple-choice, true/false or short answer questions, each with an explanation of the solution.
How a math quiz app helps you study
Some students want a math quiz app that works from the notes they already have instead of a generic question bank. DeckOwl reads your lecture slides, PDFs and photographed worksheets, then writes questions that match the topics and notation in your course.
- Multiple-choice questions with distractors based on common errors, such as sign mistakes or dropped exponents
- True/false items that test a rule, like whether a derivative or identity holds in general
- Short answer questions that ask you to show the result of a calculation, not just pick it
- Explanations that walk through the solution so you can see where your reasoning diverged
Questions from your material
Upload a PDF, DOCX, PPTX, plain text notes or a photo of a worked page. The quiz follows your course's own examples and notation.
Explanations for every answer
Each question includes a short explanation, so a wrong answer shows the step you missed rather than only marking it incorrect.
Spaced repetition on Plus
On Plus, missed questions come back at increasing intervals, which helps you keep formulas and methods from earlier units.
How it works
Upload your math material
Add lecture slides, a textbook chapter, handwritten notes photographed with your phone, or a problem set.
Choose a question type
Pick multiple choice, true/false or short answer, then generate a quiz for the topic you are studying.
Work through the quiz
Answer in the browser, read the explanations, and retry the questions you missed until the method is automatic.
Math practice works best when you answer questions from memory and then check the steps. Short quizzes on one unit, followed by a few questions from earlier units, show you which methods are solid and which need another pass before an exam.

Frequently asked questions
How many questions should I put in a math quiz?
Start with 10 to 15 questions on one topic, such as linear equations or fractions, so a wrong answer points to a specific gap. Mixing in a few questions from earlier units helps you keep older methods from fading.
Is answering quiz questions better than rereading worked examples for math?
Answering questions without looking at the solution, called retrieval practice, usually builds recall better than rereading. Still, read the worked steps carefully when you get an answer wrong, because the explanation is where the method becomes clear.
Can I export math quizzes to PDF or Moodle?
PDF and DOCX export are included in Plus, which costs $99.90 a year or $9.99 a month. QTI 2.1 and Moodle XML export are on Pro at $14.99 a month.
Is there a free plan for the math quiz app?
The free plan includes 3 generations per month and lets you study in the browser, and no credit card is needed to start. Students can get 40% off with a school email.
