, 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 50.
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.
