,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.
7. Mark schemes will firstly show the solution judged to be the most common response
expected from candidates. Where appropriate, alternatives answers are provided in
the notes. If examiners are not sure if an answer is acceptable, they will check the
mark scheme to see if an alternative answer is given for the method used.
