NOTE:
  • If a candidate answers a question TWICE, only mark the FIRST attempt.
  • If a candidate has crossed out an attempt of a question and not redone the question, mark
     the crossed-out version.
  • Consistent accuracy applies in ALL aspects of the marking memorandum. Stop marking the
     second calculation error.
  • Assuming answers/values in order to solve a problem is NOT acceptable.

NOTA:
  • As 'n kandidaat 'n vraag TWEE KEER beantwoord, merk slegs die EERSTE poging.
  • As 'n kandidaat 'n antwoord van 'n vraag doodtrek en nie oordoen nie, merk die
     doodgetrekte poging.
  • Volgehoue akkuraatheid word in ALLE aspekte van die nasienriglyne toegepas.
     Hou op nasien by die tweede berekeningsfout.
  • Aanvaar van antwoorde/waardes om 'n probleem op te los, word NIE toegelaat nie.
