    How to practice

    1. Open each topic and attempt every puzzle cold, writing your predicted answer first.

    2. Only then read the step-by-step solution and confirm the exact answer.

    3. Re-read the 'why candidates get it wrong' note — that is the actual interview signal.

    4. Finish with the section Q&A to rehearse explaining the rule out loud.
