What this math quiz app does and does not pay for

If you hoped a math quiz app would pay you for answering questions, DeckOwl will not do that. It is a study tool that turns your own math material into practice questions, so the return is better grades rather than cash.

Multiple-choice, true/false and short-answer questions from your own notes
Explanations for every answer, so missed questions become lessons
Spaced repetition for flashcards built from the same material
PDF, DOCX, Anki, CSV and Moodle XML exports on paid plans

Example middle school math practice questions

What is the derivative of x^3?3x^2. The power rule multiplies by the exponent and then lowers the exponent by one.

Solve for x: 2x + 6 = 14x = 4. Subtract 6 from both sides, then divide both sides by 2.

True or false: every rhombus is a square.False. A rhombus needs four equal sides, but a square also needs four right angles.

What is the sum of the interior angles of a hexagon?720 degrees. The formula (n-2) x 180 gives (6-2) x 180 = 720.

What is the probability of rolling a sum of 7 with two fair dice?1/6. Six of the 36 equally likely outcomes add up to 7.

Frequently asked questions

Does DeckOwl pay you for answering math quizzes?

No. DeckOwl is a study tool and does not pay users for completing quizzes or tasks. It helps you practice math material you already have.

How many practice problems should I do before a math test?

Short mixed sets done under test-like conditions reveal more about your gaps than long lists of one topic. Review every missed problem before moving on.

How do I study math when I check quiz answers on my own?

Attempt each problem before looking at the answer, then read the explanation for any miss and redo it without notes. Returning to missed items later works better than rereading the whole chapter.

Can I export math quizzes to Moodle?

Yes, on the Pro plan at $14.99 per month, which includes QTI 2.1 and Moodle XML export. The free plan gives 3 generations per month and browser study only.
