How a math quiz shows what you really know

Rereading worked examples can feel like progress, but a math quiz to test your knowledge shows whether you can actually solve problems without the solution in front of you. DeckOwl builds that quiz from the chapter or notes you already have, so every question reflects your course.

Upload a chapter, problem set or slides and get questions that match your course.
Check a mix of multiple-choice, true/false and short answer questions.
Read a clear explanation for every answer, including the ones you got right.
Retake missed questions later to find out which methods have actually stuck.

Example math quiz questions with answers

Solve for x: 2x + 7 = 19x = 6. Subtracting 7 from both sides and then dividing by 2 isolates x.

True or false: every prime number greater than 2 is odd.True. Any even number greater than 2 is divisible by 2, so it cannot be prime.

What is the derivative of x³?3x². The power rule multiplies by the exponent and reduces the exponent by one.

What is the area of a circle with radius 4?16π, about 50.27 square units. The area formula is πr², so π × 4² = 16π.

What is 3/4 + 1/6?11/12. Converting to a common denominator of 12 gives 9/12 + 2/12 = 11/12.

Explanations for every answer

Each question shows the correct answer and the reasoning behind it, so a wrong guess becomes a lesson.

Built from your material

Questions come from your own PDFs, DOCX files, slides, notes or photos of pages, so the quiz matches what your class actually covers.

How it works

Upload your material

Add a PDF, DOCX, PPTX, plain text file or a photo of a page from your textbook or notes.

Choose the question types

Pick multiple-choice, true/false or short answer, then generate the quiz.

Take the quiz and review

Answer in the browser, read the explanations for anything you missed, and retake the questions that gave you trouble.

Frequently asked questions

How many questions should I answer to test my math knowledge?

Ten to twenty questions on one topic is a practical range for a single sitting. Several short sessions usually reveal gaps more clearly than one long test.

What should I do after I get a math question wrong?

Read the explanation, then redo the problem on paper without looking at the answer. Come back to that question later in the week to confirm the method has stuck.

Can I export my math quiz?

Exports to PDF and DOCX are included with Plus at $39 per year or $7.99 per month, and QTI 2.1 and Moodle XML export are on Pro at $14.99 per month. The free plan includes 3 generations per month and studying in the browser.
