Why a PDF to quiz app beats rereading

Reading a 60-page lecture PDF over and over feels productive but rarely shows what you actually remember. A PDF to quiz app turns that file into questions you can answer right away.

Questions stay tied to your own PDF, slides or notes.
Each answer comes with an explanation you can read.
The free plan gives you 3 generations per month and browser study.
Plus and Pro add exports to PDF, DOCX and learning management system formats.

Example solar system quiz questions

Which planet is the largest in the solar system?Jupiter. It has more mass than all the other planets combined, so it is the biggest by a wide margin.

True or false: Venus rotates in the opposite direction from most planets.True. Venus spins backward, which is called retrograde rotation, so the Sun rises in the west there.

Why does the Moon show phases?Because the Sun lights different parts of the Moon as it orbits Earth, so the lit portion we see changes over the month.

What is the asteroid belt?A region between Mars and Jupiter filled with rocky objects left over from the early solar system.

Which element makes up most of the Sun's mass?Hydrogen, at about 73 percent by mass, with helium making up most of the rest.

Study and review

Answer in the browser, read the explanations and retake the questions you missed.

Teachers and students often run into the same problem: a long handout that is easy to reread and hard to recall. Quizzing yourself from the actual text tests recall, which is a more honest check than rereading. DeckOwl builds the questions from your own file, so the quiz matches what your course covers.

If you need a ready-made printable quiz, you can generate one from your own material instead of searching for a generic version that may not match your class.
