, Important – please note
Mark schemes are prepared by the Lead Assessment Writer and
considered, together with the relevant questions, by a panel of
subject teachers.
It must be stressed that a mark scheme is a working document. This
mark scheme has not been through the full standardisation process.
The standardisation process ensures that the mark scheme covers
the students’ responses to questions and that every associate
understands and applies it in the same correct way.
Assumptions about future mark schemes on the basis of one year’s
document should be avoided; whilst the guiding principles of
assessment remain constant, details will change, depending on the
content of a particular examination paper.
The Information to Examiners is included as a guide to how the mark
scheme will function as an operational document.
The layout has been kept consistent so that future operational mark
schemes do not appear different from these test materials.
If the printing process in your school alters the scale of a diagram,
measure the values on your printed papers and mark the scripts
accordingly.

, 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 his or her judgement
the Assessment Objectives, level of demand 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.
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. Different
terms in the mark scheme are shown by a / ; eg allow smooth / free movement.
2.4 Any wording that is underlined is essential for the marking point to be awarded.
