Grade 9 paper 2 Mark scheme Grade 8 & 9 SPECIMEN PAPERS , NIED, 2018 Mark Scheme Notes Marks are of the following six types: M Method mark, awarded for a valid method applied to the problem. Method marks are not lost for numerical errors, algebraic slips or errors in units. However, it is not usually sufficient for a candidate just to indicate an intention of using some method or just to quote a formula; the formula or idea must be applied to the specific problem in hand, by substituting the relevant quantities into the formula. Correct application of a formula without the formula being quoted obviously earns the M mark and in some cases an M mark can be implied from a correct answer. M2 means that the candidate method qualifies two marks. A Accuracy mark, awarded for a correct answer or intermediate step correctly obtained.

3 Accuracy marks cannot be given unless the associated method mark is earned (or implied). B Mark for a correct result or statement independent of method marks. correct answer only follow through mark allowed for work correctly following on from previously incorrect results. SC a special case where a mark can be given for a specific wrong solution, or a case where some standard marking practice is to be varied in the light of a particular circumstance.
