,General Marking Guidance
All candidates must receive the same treatment.
Examiners must mark the last candidate in
exactly the same way as they mark the first.
Mark schemes should be applied positively.
Candidates must be rewarded for what they have
shown they can do rather than penalised for
omissions.
Examiners should mark according to the mark
scheme not according to their perception of
where the grade boundaries may lie.
All the marks on the mark scheme are designed to be
awarded. Examiners should always award full
marks if deserved, i.e. if the answer matches the
mark scheme. Examiners should also be
prepared to award zero marks if the candidate’s
response is not worthy of credit according to the
mark scheme.
Where some judgement is required, mark schemes
will provide the principles by which marks will be
awarded and exemplification/indicative content
will not be exhaustive.
When examiners are in doubt regarding the
application of the mark scheme to a candidate’s
response, a senior examiner must be consulted
before a mark is awarded.
Crossed out work should be marked UNLESS the
candidate has replaced it with an alternative
response.

MATHEMATICS
General Instructions for Marking
1. The total number of marks for the paper is 100
2. These mark schemes use the following types of marks:
M marks: Method marks are awarded for ‘knowing a
method and attempting to apply it’, unless otherwise
indicated.
A marks: Accuracy marks can only be awarded if the
relevant method
(M) marks have been earned.
B marks are unconditional accuracy marks (independent of M
marks)
Marks should not be subdivided.
3. Abbreviations
These are some of the traditional marking abbreviations
that will appear in the mark schemes.
bod – benefit of doubt
ft – follow through
the symbol will be used for correct ft
cao – correct answer only
cso - correct solution only. There must be no errors in
this part of the question to obtain this mark
isw – ignore subsequent working
awrt – answers which round to
SC: special case
o.e. – or equivalent (and appropriate)
d or dep – dependent
indep – independent
dp decimal places
sf significant figures
The answer is printed on the paper or ag- answer given
4. All M marks are follow through.
A marks are ‘correct answer only’ (cao.), unless shown, for
example, as A1 ft to indicate that previous wrong working is to
be followed through. After a misread however, the subsequent
A marks affected are treated as A ft, but answers that don’t
logically make sense e.g. if an answer given for a probability is
>1 or
