Frequently asked questions

How many questions should a practice quiz have?

Ten to twenty questions is a common range for a single study session on one chapter. Shorter quizzes are easier to repeat, and repeating a quiz after a few days helps more than one long sitting.

How should I use the explanations after a quiz?

Read the explanation for every missed question, even the ones you guessed correctly. Then write the correct idea in your own words and retake the questions that tripped you up.

Can I export the quiz to Moodle?

Moodle XML export is included on the Pro plan at $14.99 per month. PDF and DOCX export are included on Plus, and the free plan lets you study in the browser without exports.

Do I need a credit card to try it?

No. You can start on the free plan with 3 generations per month without entering a credit card. Students with a school email get 40% off a paid plan.
