Mathematical Literacy/P1 2 NW/November 2024 Grade 10 – Marking Guidelines NOTE:  If a candidate answers a question TWICE, only mark the FIRST attempt.  If a candidate has crossed out (cancelled) an attempt to a question and NOT redone the solution, mark the crossed out (cancelled) version.  Consistent accuracy (CA) applies in ALL aspects of the marking guidelines; however, it stops at the second calculation error.  NOTE: consistent accuracy (CA) does not apply in cases of a breakdown.  If the candidate presents any extra solution when reading from a graph, table, layout plan and map, then penalize for every extra item presented.  General principle of marking, if a candidate makes one mistake one mark is deducted.  Rounding is an independent mark.  A conclusion mark can only be given if relevant calculations precedes it.
