_____________________________________________________________________________________ • 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.

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 and can be used if you are using the annotation facility on ePEN:
_____________________________________________________________________________________ • bod – benefit of doubt
_____________________________________________________________________________________ • ft – follow through
_____________________________________________________________________________________ o 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)
_____________________________________________________________________________________
• d… or dep – dependent
_____________________________________________________________________________________
• indep – independent
_____________________________________________________________________________________
• dp – decimal places
_____________________________________________________________________________________
• sf – significant figures
_____________________________________________________________________________________
• – The answer is printed on the paper or ag- answer given
_____________________________________________________________________________________
_____________________________________________________________________________________ • or d… – The second mark is dependent on gaining the first mark
_____________________________________________________________________________________
4. All 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 manifestly
_____________________________________________________________________________________ absurd answers should never be awarded A marks.
