Build a useful mistake bank.

The idea in plain language

A mistake collection should help explain errors rather than become a list of failures.

Start with the reason behind the idea. Reading it once can create familiarity; explaining it in a different example is a better way to check what you understood.

What to notice

Describe the information you have, and name anything that remains uncertain. Avoid filling in the missing part just because the situation looks familiar.

A useful response

Group errors by misunderstanding, wording or missing knowledge.

Take it into your next session

Choose a small example of your own. Explain the clue, the reason and the response in that order, then make a note of what you would check with an official source or instructor.

Keep a thought for later
