Why build a practice test from your own notes

Many students and teachers want a practice test from notes because a test written from your own material checks what you actually learned in class. Generic quizzes often cover ideas your course skipped, so a test built from your notes shows the gaps that matter for your exam.

  • Works with PDFs, DOCX, PPTX, plain text and photos of pages
  • Multiple-choice, true/false and short answer questions with explanations
  • Free plan includes 3 generations per month, studied in the browser
  • Plus and Pro add exports for printing, Word, and learning management systems
Example Pythagorean theorem practice questions
In a right triangle with legs 3 and 4, what is the length of the hypotenuse?5. Using a² + b² = c², 9 + 16 = 25, so c = 5.
True or false: the Pythagorean theorem applies to any triangle.False. It only applies to right triangles, where c is the side opposite the right angle.
A 10 m ladder leans against a wall with its base 6 m from the wall. How high up the wall does it reach?8 m. 10² = 6² + b² gives 100 = 36 + b², so b² = 64 and b = 8.
Which side of a right triangle is the hypotenuse?The longest side, opposite the right angle. It is the c in a² + b² = c².
Is a triangle with sides 5, 12 and 13 a right triangle?Yes. 5² + 12² = 25 + 144 = 169 = 13², so the angle opposite the side of length 13 is a right angle.

Questions drawn from your notes

Upload PDFs, DOCX files, slides, plain text or a photo of a page, and the AI writes questions based on that material.

Three question types

Choose multiple-choice, true/false or short answer questions, and read an explanation for each correct answer.

Export when you need it

Plus adds PDF and DOCX export. Pro adds QTI 2.1 and Moodle XML export for learning management systems.

How it works

Upload your notes

Add a PDF, DOCX, PPTX, text file or a photo of your pages. No credit card is needed to start.

Choose the question types

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

Take the test and review

Answer the questions, then read the explanations for anything you missed and study those parts again.

DeckOwl reads your uploaded material and writes multiple-choice, true/false or short answer questions, each with an explanation. You can take the test in the browser, and you can export it as a PDF or DOCX file on the Plus plan, or as QTI 2.1 or Moodle XML on Pro.

Work through the questions once without looking at your notes, then review the explanations for every wrong answer. Repeat the test a few days later to see what you remember.

Frequently asked questions

How many questions should a practice test on the Pythagorean theorem include?

Ten to fifteen questions cover the main ideas well: finding a missing side, identifying the hypotenuse, and checking whether a triangle is right. Mix a few word problems in with the straightforward calculations.

What should a practice test on the Pythagorean theorem cover?

It should cover the formula a² + b² = c², identifying the hypotenuse opposite the right angle, solving for a missing leg or hypotenuse, and using the converse to test whether a triangle is right. Real-world problems such as ladders and distances help show when the theorem applies.

Can I export my practice test to Word?

Yes, DOCX export is included on the Plus plan, which is $99.90 per year or $9.99 per month, and it also includes PDF export. The free plan lets you study in the browser without exports.

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.
