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.•Crossed out work should be marked UNLESS the candidate has replaced it with an alternative response. www.mymathscloud.com
PEARSON EDEXCEL GCE MATHEMATICSGeneral Instructions for Marking1.The total number of marks for the paper is 752.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.AbbreviationsThese 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)•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 mark4.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.www.mymathscloud.com
5.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. 6.If a candidate makes more than one attempt at any question:•If all but one attempt is crossed out, mark the attempt which is NOT crossed out.•If either all attempts are crossed out or none are crossed out, mark all the attempts and score the highest single attempt.7.Ignore wrong working or incorrect statements following a correct answer.www.mymathscloud.com
