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 at the
second calculation error.
• Assuming answers/values in order to solve a problem is NOT acceptable.
LET WEL:
• As 'n kandidaat 'n vraag TWEE KEER beantwoord, sien slegs die EERSTE poging na.
• As 'n kandidaat 'n antwoord van 'n vraag doodtrek en nie oordoen nie, sien die doodgetrekte
poging na.
• Volgehoue akkuraatheid word in ALLE aspekte van die nasienriglyne toegepas. Hou op nasien
by die tweede berekeningsfout.
