Where a student is unhappy with the grade awarded for a particular exam, a clerical check or review of marking may be requested. The student will be required to acknowledge that his grade may be confirmed; raised or lowered and will be responsible for paying the relevant fee. The decision as to whether to support such an enquiry will be made by the school based on several factors, including knowledge of the exam system and professional judgement. Appeals may only be made against the processes that lead to the assessment and not against the mark or grade submitted by the centre moderation.
