Pick a question and start solving now.

Your first run, step by step.

1. 01

   Choose a paper or a practice range.

   Pick a year and a paper, or select the topics and question numbers you need. The number of questions and the saving rules are shown before you begin.

2. 02

   Choose how to solve.

   ‘One at a time’ shows the answer and explanation after each question. Choose ‘all at once’ to solve the whole paper first and mark it at the end, like an exam.

3. 03

   Use the hint before the explanation.

   Try again with the hint before reading the explanation. If you are still stuck, open the explanation or talk to the helper, which asks questions instead of giving the answer (after sign-in). Topic and question-number drills let you choose the amount, but they are not saved as a paper result.

4. 04

   Save what you want to see again.

   Signing in alone moves nothing to your account. On the web, connect your account on the result screen, tick the saving consent and press the button that saves the records; in the app, finish the paper while signed in and choose ‘agree and save’. Handwriting grading needs a sign-in and a submission.

Check these before you start.

Device

Works in the browser on a phone or laptop with nothing to install, and you can also install the app from the App Store on iPhone and iPad or from Google Play on Android. To write on the question itself, a tablet in landscape with a pen is the most comfortable.

When you need to sign in

Practice starts without a sign-in. Saving to an account, handwriting grading and helper conversations need one; signing up with a Kakao, Google or Apple account asks you to confirm you are 14 or older and to agree to the privacy policy.

What is included

Handwriting grading and helper conversations have a daily limit on free accounts. Care, where the teacher and an assistant read and comment on your handwriting and mistakes, is a paid monthly subscription; the price and how to apply are shown on the app's account screen.

Can I come back to what I solved?

If you want to see it again later, check how it is saved. What remains depends on how you practised.

If you finished a whole paper

On the web, the result screen asks whether to save this result to your account: connect your account, tick the saving consent and press the save button, which shows how many records it saves. If you don't, the result stays only in this browser, and signing in later does not move it. In the app, finishing a paper while signed in asks whether to save it to your account as well; ‘agree and save’ saves this paper and the ones after it, the same as turning on account saving on the account screen. Records solved on this device before you signed in are not uploaded.

If you drilled by topic or question number

It is not saved as a paper result. Read the saving note before you start.

Time spent per question

It stays only in the browser you solved on and is not saved to the account. ‘Revisit slow questions’ lets you practise them again; that second attempt is marked but not recorded.

Your handwriting

It is saved when you sign in, confirm the answer the app read, and submit. Writing you have not submitted is lost on a refresh.
