Frequently asked questions

How many practice questions should I do in one session?

A short set of 10 to 15 questions is a practical starting point for one sitting. Spacing sessions across several days usually helps more than one long cram.

How do I know if I really understand a topic?

Try answering questions without looking at your notes, then read the explanation for every miss. If you can explain why each answer is correct in your own words, you are likely ready.

Can I export my quiz?

Exports are paid features. Plus at $39/year or $7.99/month includes PDF, DOCX, Anki and CSV export, and Pro at $14.99/month adds QTI 2.1 and Moodle XML.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser, with no exports, and you don't need a credit card to start.
