Edexcel dialect
After a lesson — mark like Pearson marks
- Write the method line that earns the M mark — not only the final number.
- Keep exact forms until the question asks to approximate.
- Watch dependent accuracy: an early slip can wipe later A marks.
- Self-mark with a WCH12 scheme, then second-pass here.
