If in doubt, read the entire answer and then the question paper and marking guidelines. Ask yourself or your senior marker if the response could ΄fit΄ into the marking guidelines before allocating the correct marks to the candidate. For example, the marking guidelines state 'cheap' and the learner responds with 'less expensive'.  Beware of overlapping answers to a specific question. In general, one mark is awarded per fact.
