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,

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.

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).

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)

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)

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,

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.

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

If you make a mistake, just put a LINE
THROUGH it—NEVER use liquid paper.
