Reading Time - 5 minutes (work out your plan of attack!) Working time = 2 1/2 hours (allow 30 minutes for Section I and 2 hours for Section II – 20 minutes for each question) Write using blue or black pen Calculators may be used A formula sheet is provided at the back of the paper. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 20 HSC General Exam Equipment You may only take the equipment listed in the next slide into the examination room. No other equipment is allowed. Any equipment brought into the examination room may be subject to inspection before the examination commences. It is the student’s responsibility to supply equipment that is in good working order. This includes calculators. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 21 HSC General Exam Equipment Students are expected to provide pens (black is recommended), pencils and erasers, and a ruler marked in millimetres and centimetres, for ALL EXAMINATIONS. Students may use a pencil sharpener and/or highlighter pen. For the General Mathematics exam: A calculator (see slide 23 for details) A pair of compasses A protractor Set squares (optional) a curve drawing template (see slide 24 for details) Curriculum and Learning Innovation Centre, Mathematics & Numeracy 22 HSC General Exam Calculator In the General Mathematics HSC examination students are permitted to use calculators, including graphics calculators. Note: Calculators must be handheld and silent in operation. Permitted devices must be primarily calculators. For example, devices that include a calculator function among other ‘apps’ or which incorporate a QWERTY keyboard are NOT permitted. Calculators that also operate as communication devices are NOT permitted. All memories and storage facilities must be cleared before the calculator is brought into the examination room (see www.boardofstudies.nsw.edu.au/hsc_exam s/calculators.html ). Memory cards or other peripheral devices must not be brought into the examination room. (taken from HSC Examination Timetable 2011, NSW BOS, page 2) Curriculum and Learning Innovation Centre, Mathematics & Numeracy 23 HSC General Exam curve drawing template Students may take into the HSC mathematics examination templates for drawing curves and geometrical figures, measuring, constructing etc. Such templates may contain equations of simple curves (eg y=x², y=sin x, y=1/x) that can be drawn using the template, and decimal approximations (eg for pi, e), but no other printed formulae (eg sine rule, cosine rule, quadratic formulae, area and volume formulae). Acceptable templates include Mathomat, Mathomat Senior and Mathaid (Non Formulae).

Curriculum and Learning Innovation Centre, Mathematics & Numeracy 25 Back to content Exam formulae sheet • • • • • All the information on this two page sheet will be given to you in the exam Just tear off the formulae sheet from the back of the paper to use during your exam Practice using this sheet when you are studying Here are two pages of formulae that you don't need to remember What you do need to know is when and how to use the formulae Curriculum and Learning Innovation Centre, Mathematics & Numeracy 26 HSC MARKING PROCESS Curriculum and Learning Innovation Centre, Mathematics & Numeracy 27 An Overview of the Marking Process for the HSC General Mathematics Exam MARKING GUIDELINES, developed by the examination committee, are given for all questions – these guidelines indicate the process for which marks will be allocated. PART MARKS for each question are awarded according to the guidelines. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 28 An Overview of the Marking Process for the HSC General Mathematics Exam HALF MARKS are never used –full marks may be awarded before the correct numerical answer is reached TRANSCRIPTION ERRORS (which do not make the question easier) are not penalised. (incorrect substitution into a formula is NOT a transcription error) Back to content Curriculum and Learning Innovation Centre, Mathematics & Numeracy 29 EXAMINER’S COMMENTS Curriculum and Learning Innovation Centre, Mathematics & Numeracy 30 Examiners’ Comments HSC General Mathematics SHOW substitutions and working out clearly— marks are allocated for the PROCESS and the answer, not just the answer. Watch the number of MARKS allocated to each part of the question — don’t write half a page of explanation for 1 mark! Curriculum and Learning Innovation Centre, Mathematics & Numeracy 31 Examiners’ Comments HSC General Mathematics Take CARE—make sure you recall the FORMULA correctly — marks lost from careless errors are as ‘expensive’ as marks lost by not doing the more difficult questions. You have to WRITE the CORRECT FORMULA and SUBSTITUTE correctly into it in order to be awarded a mark. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 32 Examiners’ Comments HSC Mathematics When PROVING or SHOWING a given result, check that your answer is the SAME as the result given in the paper! CORRECT answers from INCORRECT working are not awarded marks - if you have made a mistake, fix the error in EVERY line of working don’t fudge! Curriculum and Learning Innovation Centre, Mathematics & Numeracy 33 Examiners’ Comments HSC Mathematics LINK parts of a question—If (a) has parts (i) and (ii), often using the result in (i) makes answering (ii) easier. If a question has multiple parts, check that you have answered the question in the CORRECT part. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 34 Examiners’ Comments HSC Mathematics Draw large, clear DIAGRAMS in pencil—about 1/3 a page is a good size and mark on it all given information. Use your diagram to PLAN your response (if you think it, write it on your diagram) If drawing axes, use a RULER, start the horizontal axis on a line and mark off points EVENLY. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 35 Examiners’ Comments HSC Mathematics Write working out CLEARLY—some students can’t read their own writing, so markers have some difficulty awarding marks. (i.e. ‘r’ & ‘n’ & ‘x’ often look similar, as do 5 & 8 and 4 & 9) Curriculum and Learning Innovation Centre, Mathematics & Numeracy 36 Examiners’ Comments HSC Mathematics Read the question carefully — watch for KEYWORDS and HIGHLIGHT. e.g. 3 significant figures. Check at the end of each part that you have ANSWERED THE QUESTION THAT WAS ASKED. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 37 Examiners’ Comments HSC Mathematics Use NOTATION and TERMINOLOGY correctly. From the syllabus: Outcome H11 A student uses mathematical argument and reasoning to evaluate conclusions drawn from other sources, communicating his/her position clearly to others Don’t contradict yourself (BOS NSW, General Mathematics Stage 6 syllabus, 1999) Curriculum and Learning Innovation Centre, Mathematics & Numeracy 38 Examiners’ Comments HSC General Mathematics If using a graphics calculator, write the list of substitutions so you can gain marks towards the answer even if it is incorrect. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 39 Examiners’ Comments HSC General Mathematics Make sure you stay inside the margins on each page of your writing booklet, as markers receive the pages vertically as electronic Adobe files. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 40 Examiners’ Comments HSC General Mathematics You may have to justify or explain your answer. Be familiar with the appropriate terminology and read answers after writing them to ensure they make sense. Keep an eye on the TIME—don’t spend so long on the early questions you don’t get to the last few questions. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 41 Examiners’ Comments HSC Mathematics Use the FORMULA SHEET provided. There is no excuse for an incorrect formula! When using a CALCULATOR, don’t round off too early and watch for radians/degrees. Markers can see correct rounding, even if the answer is incorrect. Check that your answer is REASONABLE. Curriculum and Learning Innovation Centre, Mathematics & Numeracy 42 Examiners’ Comments HSC Mathematics If you make a mistake, just put a LINE THROUGH it—NEVER use liquid paper.
