MARKSCHEME November 2002 MATHEMATICS Higher Level Paper 2 25 pages N02/510/H(2)M+ INTERNATIONAL BACCALAUREATE BACCALAURÉAT INTERNATIONAL BACHILLERATO INTERNACIONALc Paper 2 Markscheme Instructions to Examiners 1 Method of marking (a) All marking must be done using a red pen. (b) Marks should be noted on candidates’ scripts as in the markscheme: y show the breakdown of individual marks using the abbreviations (M1), (A2) etc. y write down each part mark total, indicated on the markscheme (for example, [3 marks] ) – it is suggested that this be written at the end of each part, and underlined; y write down and circle the total for each question at the end of the question. 2 Abbreviations The markscheme may make use of the following abbreviations: M Marks awarded for Method A Marks awarded for an Answer or for Accuracy G Marks awarded for correct solutions, generally obtained from a Graphic Display Calculator, irrespective of working shown C Marks awarded for Correct statements R Marks awarded for clear Reasoning AG Answer Given in the question and consequently marks are not awarded 3 Follow Through (ft) Marks Questions in this paper were constructed to enable a candidate to: x show, step by step, what he or she knows and is able to do; x use an answer obtained in one part of a question to obtain answers in the later parts of a question. Thus errors made at any step of the solution can af fect all working that follows. Furthermore, errors made early in the solution can affect more steps or parts of the solution than similar errors made later. To limit the severity of the penalty for errors made at any step of a solution, follow through (ft) marks should be awarded. The procedures for awarding these marks require that all examiners: (i) penalise an error when it first occurs; (ii) accept the incorrect answer as the appropriate value or quantity to be used in all subsequent parts of the question; – 3 – N02/510/H(2)M+
