Train the moment before the calculation.
Encounter → Recognise → Attempt → Diagnose → Practise → Retest → Improve.
Look for a relationship, not a keyword.
Read an unfamiliar question without a topic label. Choose a useful first move and explain what in the question suggested it. The feedback shows the clue, accepts stored valid alternatives and distinguishes a wrong method from a longer valid method.
Use hints deliberately
Start with a recognition hint. If needed, move to a method hint, then an opening demonstration. Full solutions are separate. Hinted attempts are recorded so they are not confused with unassisted recognition.
Return with a purpose
Wrong recorded openings build a private Error Bank. Review the misconception, write a note and try targeted practice. Use unseen assessments to check whether your thinking transfers, subject to question availability.
Give progress enough time
A repeat correct answer can show familiarity. It does not alone establish transfer or mastery. First-attempt accuracy, unassisted accuracy and response time are shown separately.
