How an AI practice test generator helps you study

A practice test is most useful when it asks about the exact pages your class covered, and an AI practice test generator can build one from those pages in a few minutes. You upload the lecture slides, chapter PDF or typed notes, and the tool writes questions that match that material rather than generic trivia.

  • Multiple-choice, true/false and short answer questions from one upload
  • Explanations for each answer, including the wrong ones
  • Study in the browser on the free plan with 3 generations per month
  • Export to PDF or DOCX on Plus, and QTI 2.1 or Moodle XML on Pro
Example cell biology practice questions (sample topic)
Which organelle produces most of the cell's ATP?The mitochondrion. It carries out cellular respiration, which converts glucose and oxygen into ATP.
True or false: Water moves by osmosis from the side with higher solute concentration to the side with lower solute concentration.False. Water moves from the side with lower solute concentration to the side with higher solute concentration.
Short answer: What is the role of the Golgi apparatus?It modifies, sorts and packages proteins and lipids into vesicles. It acts as the cell's shipping center, receiving products from the endoplasmic reticulum.
Which phase of mitosis is when sister chromatids separate?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.
Which type of bond holds complementary DNA strands together?Hydrogen bonds between base pairs. They are weak individually, which lets the strands separate during replication.

Three question formats

Multiple-choice, true/false and short answer questions, each with an explanation for the correct answer.

Built from your material

Upload PDFs, DOCX, PPTX, plain text or photos of pages, and the questions come from what you actually studied.

Export when you need it

The free plan studies in the browser. Plus adds PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML export.

How it works

Upload your material

Add a PDF, slides, a Word file, notes or a photo of a page.

Choose the question types

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

Take the test and review

Answer each question, read the explanation, and retake the questions you missed.

Each question comes with an explanation, so a wrong answer becomes a lesson instead of a dead end. Short answer questions are especially useful because they make you recall the idea without seeing the options first, which is closer to what most exams ask.

The free plan lets you study in the browser with 3 generations per month. Plus adds unlimited generations and PDF or DOCX export, and Pro adds QTI 2.1 and Moodle XML export for learning management systems.

Frequently asked questions

How many practice questions should I make for a chapter exam?

Twenty to thirty questions covers most single chapters well enough to find your weak spots. Mix question types so you practice both recognizing answers and writing them from memory.

What is the best way to use a practice test before an exam?

Take the test closed-book, then check every explanation, including for questions you got right. Retake only the missed questions a day or two later, since spaced repetition beats rereading notes.

Can I export the practice test to PDF or DOCX?

Yes, PDF and DOCX export are included on the Plus plan, which costs $39/year or $7.99/month. The free plan lets you study in the browser without exports.

Does DeckOwl need a credit card to start?
