, General Marking Guidance
Question 1 continued
_____________________________________________________________________________________ • All candidates must receive the same treatment. Examiners must mark the first candidate
DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA
DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA
_____________________________________________________________________________________ in exactly the same way as they mark the last.
_____________________________________________________________________________________ • Mark schemes should be applied positively. Candidates must be rewarded for what they
_____________________________________________________________________________________ have shown they can do rather than penalised for omissions.
_____________________________________________________________________________________ • Examiners should mark according to the mark scheme not according to their perception of
where the grade boundaries may lie.
_____________________________________________________________________________________
• There is no ceiling on achievement. All marks on the mark scheme should be used
_____________________________________________________________________________________
appropriately.
_____________________________________________________________________________________
• All the marks on the mark scheme are designed to be awarded. Examiners should always
_____________________________________________________________________________________
award full marks if deserved, i.e. if the answer matches the mark scheme. Examiners
_____________________________________________________________________________________
should also be prepared to award zero marks if the candidate’s response is not worthy of
_____________________________________________________________________________________
credit according to the mark scheme.
_____________________________________________________________________________________
• Where some judgement is required, mark schemes will provide the principles by which
_____________________________________________________________________________________
marks will be awarded and exemplification may be limited.
_____________________________________________________________________________________
• When examiners are in doubt regarding the application of the mark scheme to a
_____________________________________________________________________________________
candidate’s response, the team leader must be consulted.
_____________________________________________________________________________________
• Crossed out work should be marked UNLESS the candidate has replaced it with an
_____________________________________________________________________________________ alternative response.
