What is Practice Your Mistakes?
Sign-in requiredPractice Your Mistakes is one of our K-12 Learning Tools. Every K-12 question you ever missed, queued up for spaced-repetition review. Get three correct in a row and it leaves the queue. Work through it at your own pace — each step explains itself, so you can use it for study or teaching without extra preparation. It runs on our servers, so it needs a free AnythingText account to use — AI-powered tools may also require an active plan. More in this collection: Grade-specific review quizzes from Kindergarten through Grade 12.

Frequently Asked Questions
Is Practice Your Mistakes free?
You need a free AnythingText account to use it, because it runs on our servers rather than in your browser. AI-powered tools also draw on a paid plan — the pricing page lists what each plan includes.
Do I need to create an account?
Yes — sign in with Google and you can start straight away. The account exists so the server-side run can be attributed and rate-limited fairly.
What happens to my data?
Your input is sent to our server, used to produce the result, and not stored afterwards. Tools that call an AI provider are covered in detail on our AI processing page.
Can I use Practice Your Mistakes with a class?
Yes. It is free and needs no student accounts, so you can put it on a projector or send the link to a whole class.
Do I need to install anything?
No. Practice Your Mistakes runs in the browser on desktop, tablet, and phone. There is nothing to download and nothing to keep updated.
More detail on plans is on our pricing page, and how AI-powered tools handle your data is covered on the AI processing page.
