  • SC marks are given in special cases as mentioned in the mark scheme.
  • FT will indicate the award of follow through marks when the mark scheme allows it.


  • cao – correct answer only
  • dep – dependent on another mark
  • eeo – each error or omission
  • isw – ignore subsequent working
  • oe – or equivalent
