General Marking Guidance
All candidates must receive the same treatment.
Examiners must mark the first candidate in exactly
the same way as they mark the last.
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.
There is no ceiling on achievement. All marks on the mark
scheme should be used appropriately.
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 may be limited.
When examiners are in doubt regarding the application of the
mark scheme to a candidate’s response, the team
leader must be consulted.
Crossed out work should be marked UNLESS the candidate has
replaced it with an alternative response.

EDEXCEL GCE MATHEMATICS
General Instructions for Marking
1. The total number of marks for the paper is 100.
2. The Edexcel Mathematics 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
oe – or equivalent (and appropriate)
dep – dependent
indep – independent
dp decimal places
sf significant figures
🞸 The answer is printed on the paper
The second mark is dependent on gaining the first mark
4. For misreading which does not alter the character of a question or
materially simplify it, deduct two from any A or B marks gained, in that
part of the question affected.
5. Where a candidate has made multiple responses and indicates which
response they wish to submit, examiners should mark this response.
If there are several attempts at a question which have not been crossed out,
examiners should mark the final answer which is the answer that is the
most complete.
6. Ignore wrong working or incorrect statements following a correct answer.
