AQA Mathematics Paper 2 Mark scheme

2. 3. AS 4. Mathematics 5. Paper 2 6. Mark scheme 7. 8. Specimen 9. 10. Version 2.0 11. Mark schemes are prepared by the Lead Assessment Writer and considered, together with the relevant questions, by a panel of subject teachers. This mark scheme includes any amendments made at the standardisation events which all associates participate in and is the scheme which was used by them in this examination. The standardisation process ensures that the mark scheme covers the students’ responses to questions and that every associate understands and applies it in the same correct way. As preparation for standardisation each associate analyses a number of students’ scripts. Alternative answers not already covered by the mark scheme are discussed and legislated for. If, after the standardisation process, associates encounter unusual answers which have not been raised they are required to refer these to the Lead Assessment Writer. 12. It must be stressed that a mark scheme is a working document, in many cases further developed and expanded on the basis of students’ reactions to a particular paper. Assumptions about future mark schemes on the basis of one year’s document should be avoided; whilst the guiding principles of assessment remain constant, details will change, depending on the content of a particular examination paper. 13. 14.

Mark scheme instructions to examiners 17. General 18. The mark scheme for each question shows: 19. the marks available for each part of the question 20. the total marks available for the question 21. marking instructions that indicate when marks should be awarded or withheld including the principle on which each mark is awarded. Information is included to help the examiner make his or her judgement and to delineate what is creditworthy from that not worthy of credit 22. a typical solution. This response is one we expect to see frequently. However credit must be given on the basis of the marking instructions. 23. If a student uses a method which is not explicitly covered by the marking instructions the same principles of marking should be applied. Credit should be given to any valid methods. Examiners should seek advice from their senior examiner if in any doubt. 24. Key to mark types 25. M mark is for method 26. 27. dM mark is dependent on one or more M marks and is for method R mark is for reasoning 28. mark is dependent on M or m marks and is for accuracy 29. 30. mark is independent of M or m marks and is for method and accuracy 31. mark is for explanation 32. follow through from previous incorrect result 33.
