The subject grade is assigned based on the candidate's demonstration of his/her mastery of the learning outcomes in the entire curriculum as well as the level of cognitive demand expected for the subject. In a given subject, the mode and format of assessment for each paper and the coverage of topics may differ. In addition, given the different nature and requirements for each subject as well as different weightings of the paper, there would not be a consistent way to interpret the paper grades meaningfully. Such an approach is consistent with that of other examination boards as the subject grade is a more valid and reliable measure of the students overall performance.
