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 WCH15 scheme, then second-pass here.

Marking desk
