Past paper, marked like an examiner
Take one question from a real past paper, answer it, then read the mark scheme aloud and show exactly where the two lost marks went. Nothing else builds a parent's trust this quickly.
- A-Level P4 mechanics: where students drop two of the six marks
- O-Level physics — what 'explain' actually wants in the mark scheme
- IGCSE maths transformation question, done and then marked
