Mark Scheme (Results) October 2020 Pearson Edexcel IAL Mathematics (WMA12) Pure Mathematics P2

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. General Instructions for Marking 1. The total number of marks for the paper is 75. 2. The Pearson 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 • the symbol or ft 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.
