Information to Examiners
1. General
The mark scheme for each question shows:
the marks available for each part of the question
the total marks available for the question
the typical answer or answers which are expected
extra information to help the examiner make their judgement
the Assessment Objectives and specification content that each question is intended to cover.
The extra information is aligned to the appropriate answer in the left-hand part of the mark scheme and
should only be applied to that item in the mark scheme.
At the beginning of a part of a question a reminder may be given, for example: where consequential
marking needs to be considered in a calculation; or the answer may be on the diagram or at a different
place on the script.
In general the right-hand side of the mark scheme is there to provide those extra details which confuse
the main part of the mark scheme yet may be helpful in ensuring that marking is straightforward and
consistent (for example, a scientifically correct answer that could not reasonably be expected from a
student’s knowledge of the specification).
2. Emboldening and underlining
2.1 In a list of acceptable answers where more than one mark is available ‘any two from’ is used, with
the number of marks emboldened. Each of the following bullet points is a potential mark.
