Resource overview

This markscheme is listed under Mathematics — previous courses in the 2012 examination archive. Its catalogue level is HL. The catalogue session is May. The information below helps you identify the document before opening the complete PDF. Subject, year and session labels come from the archive catalogue; the original cover remains the reference if a label differs. A file is not automatically suitable for your current syllabus simply because its subject name matches.

Use this markscheme alongside its matching question paper. Attempt the questions first, then compare the required reasoning and the available marks. Record the exact step that lost credit rather than only the final answer. Examiner wording can help you distinguish a calculation error from missing explanation, but an older markscheme may use a previous assessment structure.

M12/5/MATHL/HP3/ENG/TZ0/SP/M 12 pages MARKSCHEME May 2012 MATHEMATICS STATISTICS AND PROBABILITY Higher Level Paper 3 – 2 – M12/5/MATHL/HP3/ENG/TZ0/SP/M Instructions to Examiners Abbreviations M Marks awarded for attempting to use a correct Method; working must be seen. (M) Marks awarded for Method; may be implied by correct subsequent working. A Marks awarded for an Answer or for Accuracy; often dependent on preceding M marks. (A) Marks awarded for an Answer or for Accuracy; may be implied by correct subsequent working. R Marks awarded for clear Reasoning. N Marks awarded for correct answers if no working shown. AG Answer given in the question and so no marks are awarded. Using the markscheme 1 General Mark according to scoris instructions and the document “Mathematics HL: Guidance for e-marking May 2012”. It is essential that you read this document before you start marking. In particular, please note the following. Marks must be recorded using the annotation stamps. Please check that you are entering marks for the right question.  If a part is completely correct , (and gains all the ‘must be seen’ marks), use the ticks with numbers to stamp full marks.  If a part is completely wrong, stamp A0 by the final answer.  If a part gains anything else, it must be recorded using all the annotations. All the marks will be added and recorded by scoris. 2 Method and Answer/Accuracy marks  Do not automatically award full marks for a correct answer; all working must be checked, and marks awarded according to the markscheme.  It is not possible to award M0 followed by A1, as A mark(s) depend on the preceding M mark(s), if any.  Where M and A marks are noted on the same line, e.g. M1A1, this usually means M1 for an attempt to use an appropriate method ( e.g. substitution into a formula) and A1 for using the correct values.  Where the markscheme specifies (M2), N3, etc., do not split the marks.  Once a correct answer to a question or part-question is seen, ignore further working.
