•
– there may be more space than you need.
You should show sufficient working to make your methods clear. Answers without
•
working may not gain full credit.
Inexact answers should be given to three significant figures unless otherwise stated.
Information
•• A booklet ‘Mathematical Formulae and Statistical Tables’ is provided.
• There are 9 questions in this question paper. The total mark for this paper is 75.
The marks for each question are shown in brackets
– use this as a guide as to how much time to spend on each question.
Advice

, General Marking Guidance
Question 1 continued • All candidates must receive the same treatment. Examiners must mark the first
_____________________________________________________________________________________ candidate in exactly the same way as they mark the last.
DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA
DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA DO NOT WRITE IN THIS AREA
_____________________________________________________________________________________ • 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.

Question 1 continued
_____________________________________________________________________________________ 1. The total number of marks for the paper is 75.

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.
