How the quiz is built from your material

Practice tests lose their value when they don't match what your instructor covered. The right online quiz application for students starts from your own slides, PDFs or notes, so every question tests the material you actually have to know.

Multiple-choice, true/false and short-answer questions from any study file
Explanations for every answer, right or wrong
Flashcards with spaced repetition and mind maps alongside quizzes
Exports to PDF, DOCX, Anki and CSV on Plus, with QTI and Moodle XML on Pro

Example intro biology quiz questions

Which organelle is the main site of ATP production in eukaryotic cells?The mitochondrion. It carries out cellular respiration, which produces most of the cell's ATP.

True or false: plant cell walls are made mainly of cellulose.True. The rigid cell wall gives plants structure, and cellulose is its main component.

What is the main function of ribosomes?Protein synthesis. Ribosomes translate mRNA into chains of amino acids that form proteins.

Why does a plant cell shrink when placed in concentrated salt water?The salt solution is hypertonic, so water leaves the cell by osmosis, moving toward the side with more solute.

Which phase of mitosis lines chromosomes up along the cell's equator?Metaphase. Spindle fibers align the chromosomes at the metaphase plate before they separate in anaphase.

Reads your own material

PDF, DOCX, PPTX, plain notes and photos of pages are all read, so every question comes from what your class actually covered.

Explains every answer

Each multiple-choice, true/false or short-answer question includes an explanation, so a wrong answer teaches you what to review.

Exports when you need it

Plus exports to PDF, DOCX, Anki and CSV. Pro adds QTI 2.1 and Moodle XML for courses that run on an LMS.

How it works

Upload your notes

Add a PDF, slide deck, DOCX file, text notes or photos of pages. Text recognition handles the photos.

Choose a question type

Pick multiple-choice, true/false or short-answer questions, and set how many you want from the material.

Take the quiz and review

Answer in the browser, then read the explanations and retake the questions you missed until they stick.

DeckOwl reads PDF, DOCX, PPTX and plain-text files, plus photos of pages, then writes questions with explanations for each answer. Wrong answers show why they were wrong, which turns a score into a clear list of what to review next.

Frequently asked questions

How many questions should a practice quiz have?

Ten to twenty questions cover most chapter-length reading and give enough variety to spot gaps. Shorter quizzes of five or six questions work well as a quick check before class.

How do I study cell biology effectively with practice quizzes?

Answer each question before reading the choices, then read the explanation for every miss, including the ones you guessed right. Retake the missed questions a day or two later to make them stick.

Does the free plan include exports?

No. The free plan lets you study in the browser with 3 generations per month. PDF and DOCX export start on Plus, and QTI 2.1 and Moodle XML export are included on Pro.
