Turn a wrong answer into a revision note

A mistake is the most useful thing on your page. Here is a three line way to keep it.

read the guide
turn-a-wrong-answer-into-a-revision-note.md
In short

Write what you did, what was right, and the one-sentence reason. Review the note, not the whole question.

Why mistakes beat easy wins

Getting something right tells you little. Getting it wrong shows exactly where your understanding breaks. That is worth keeping.

The three line note

  1. What I did: x = 4.
  2. What was right: x = −4.
  3. Why: I forgot to flip the sign when moving the term across.

Review it

Read your notes the day after, then a week later. Ask Doubtster to explain the step you got wrong if the reason still feels fuzzy.

AI explanations can contain mistakes. Check important answers with your teacher.
