The threshold (minimum mark) for B is set halfway between those for Grades A and C. The threshold
(minimum mark) for D is set halfway between those for Grades C and E. The threshold (minimum mark) for
G is set as many marks below the F threshold as the E threshold is above it. Grade A* does not exist at the
level of an individual component.

The thresholds for the syllabus are determined first by adding together the thresholds for the components
taken by the candidate. A reduction may be made at the higher grades depending on the correlation of the
papers. If the maximum raw marks for the components are not in the weighting/relationship specified in the
syllabus, a weighting is applied to arrive at the overall thresholds. The A* threshold is calculated using the
difference between A and B as a starting point.

The maximum total mark for this syllabus is 200.

The overall thresholds for the different grades were set as follows.
