                                         NSC/NSS – Marking Guidelines/Nasienriglyne

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 Guidelines. Stop marking at 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, sien slegs die EERSTE poging na.
   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.

Please read carefully through the following table before marking QUESTION 8–10 /
Lees asseblief sorgvuldig deur die volgende tabel alvorens VRAE 8–10 nagesien word.

               The order in which the candidate answers a geometry question must follow
               logically/ Die volgorde waarin ‘n kandidaat ‘n meetkundevraag beantwoord moet

               The candidate first needs to calculate x BEFORE he/she can calculate y/Die
               kandidaat moet eerste vir x bereken VOORDAT hy/sy vir y kan bereken.

      S
               ‘n Punt vir ‘n korrekte bewering
               (‘n Punt vir ‘n bewering is onafhanklik van die rede)
               A mark for the correct reason
               (A reason mark may only be awarded if the statement is correct)
      R
               ‘n Punt vir ‘n korrekte rede
               (‘n Punt word slegs vir die rede toegeken as die bewering korrek is)
               Award a mark if the statement AND reason are both correct
               (Both MUST be correct to get one mark)
     S/R       Ken ‘n punt toe as die bewering EN rede beide korrek is
               (Beide MOET korrek wees om een punt te kry)
