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.
2.2 A bold and is used to indicate that both parts of the answer are required to award the mark.
2.3 Alternative answers acceptable for a mark are indicated by the use of or.
Alternative words in the mark scheme are shown by a solidus eg allow smooth / free
movement.
2.4 Any wording that is underlined is essential for the marking point to be awarded.
