General marking guidance

• All candidates must receive the same treatment. Examiners must mark the last candidate in exactly the same way as they mark the first.

• Mark schemes should be applied positively. Candidates must be rewarded for what they have shown they can do rather than be penalised for omissions.

• Examiners should mark according to the mark scheme – not according to their perception of where the grade boundaries may lie.

• 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/indicative content will not be exhaustive. However different examples of responses will be provided at standardisation.

• When examiners are in doubt regarding the application of the mark scheme to a candidate’s response, a senior examiner must be consulted before a mark is given.

• Crossed-out work should be marked unless the candidate has replaced it with an alternative response.

Specific guidance for mathematics

1. These 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.

2. Abbreviations

These are some of the traditional marking abbreviations that may appear in the mark schemes.

• bod benefit of doubt

• ft follow through

• this symbol is 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

• o.e. or equivalent (and appropriate)

• d… dependentor dep

• 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

3. All M marks are follow through.

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 answers that don’t logically make sense e.g. if an answer given for a probability is >1 or

5. A pond initially contains 1000 litres of unpolluted water.

The pond is leaking at a constant rate of 20 litres per day.

It is suspected that contaminated water flows into the pond at a constant rate of 25 litres per day and that the contaminated water contains 2 grams of pollutant in every litre of water.

It is assumed that the pollutant instantly dissolves throughout the pond upon entry.

Given that there are x grams of the pollutant in the pond after t days,

(a) show that the situation can be modelled by the differential equation,

ddxt

= 50 − 4

200x

t+(4)

(b) Hence find the number of grams of pollutant in the pond after 8 days.(5)

(c) Explain how the model could be refined.(1)

6. f (x) =

xx

++

(a) Show that

∫ f (x)d x = A ln(x2 + 9) + B arctanx3

+ c

where c is an arbitrary constant and A and B are constants to be found.(4)

(b) Hence show that the mean value of f (x) over the interval [0, 3] is

16

ln 2 + 1

18π

(3)

(c) Use the answer to part (b) to find the mean value, over the interval [0, 3], of

f (x) + ln k

where k is a positive constant, giving your answer in the form p + 16

ln q, where p and q are constants and q is in terms of k.
