Question
Explain the time complexity difference between AVL and Red-Black trees.

Sample result
Why speaking
Recognising is not recalling.
When you flip a flashcard, you see the answer and think, yes, I knew that. That is recognition, and it is easy to mistake for knowing.
Speaking the answer first is harder. You have to pull the idea out of memory and put it into words before you can check it. Whatever is vague or missing shows up straight away, while there is still time to fix it.

Answer out loud in your own words, or type it if you cannot talk.
-
Grade
The AI compares your answer with the card's correct answer and lists what you covered and what you missed.
What you get
Feedback that names the gap.

Do I need an account?
Yes. You need an account to use Verbal Quiz, and the account is free. Signing up takes no credit card and has no trial period.
How does the AI grade my answer?
When you answer out loud, Verbal Quiz transcribes what you said. The AI then compares your answer with the card's correct answer and shows which ideas you covered and which you missed.
Can I type my answer instead of speaking it?
Yes. Every card can be answered by speaking or by typing, and both are graded the same way.
Is there an iOS or Android app?
Yes. Verbal Quiz works on the web, on iPhone and iPad through the App Store, and on Android through Google Play.
What subjects can I study?
Any subject where you can write a question and a correct answer. Each card has a question on the front and the correct answer on the back.
How is this different from regular flashcards?
With regular flashcards you flip the card and judge yourself. With Verbal Quiz you commit to an answer first, out loud, and then it is graded against the correct one, so gaps show up instead of hiding.
