If in doubt, read the entire answer and then the question paper and the marking guideline. o Ask yourself or your senior marker if the response could 'fit' into the marking guideline before allocating the correct marks to the candidate. o Accept correct answers that are expressed differently, e.g. the marking guideline states 'slow' and the candidate responds with 'not fast'.  Beware of overlapping answers to a specific question. In general, ONE mark is awarded per fact.  Do not choose answers on the candidate's behalf. Where a question requires a candidate to LIST or NAME/STATE: mark the first number of instances required, e.g. the first TWO facts if the candidate presents a list of FIVE facts and only TWO facts were required, even if presented in paragraph format.  Questions requiring longer answers must be regarded as a single unit. Marks can be awarded if correct statements are found anywhere in the paragraph.
