Exam Tips
BEFORE THE EXAM
Make sure that you have completed some previous exam papers
as part of your final revision under strict time conditions. Also remember to
have the answers (or mark scheme) on hand, it's
no use thinking that you have the right answers. Even the most able students
will make silly errors when working under time pressure. You need to make sure
that you concentrate enough to keep the silly errors at a minimum and also ensure
that there are no gaping holes in your maths skills.
Take
a good look at the previous papers, they are unlikely to provide sufficient
clues for you to be able to "predict" possible questions for your exam. However,
they will help you to appreciate how examiners phrase
the questions and help you appreciate the spread of knowledge you require.
The questions sometimes contain clues which will help you solve them - remember
the sort of clues which crop up and look out for these in your main exam. It's
no good only revising part of what you have learned in maths. If you want to
achieve a good grade, make sure that you can have a good attempt at all questions
(even if you can't answer the generally trickier later parts of the questions,
the earlier parts should be straightforward marks in the bag).
Strange
as it may seem, maths is actually one of the easiest topics
to revise - provided that you have understood what you have learned and
have solved lots of problems along the way to help you reinforce your understanding.
If you have done this then your maths revision should consist of testing yourself
by doing past papers, identifying areas where you've forgotten what it's all
about, solving more problems in your weak areas and that's it! No strings of
dates or foreign verbs or properties of elements in the periodic table to memorise.
Whatever you do, don't fall into the trap of thinking that maths is so easy
that you don't really need to revise at all or you'll be in for a big shock!
"THE TIME IS 9 O'CLOCK, YOU MAY NOW OPEN YOUR PAPERS"
If you've practised some past papers under timed conditions, then this hearing
this should be a challenge - rather than a death sentence!
You may have been given a couple of minutes to read
the instructions on the first page - make sure that you use these wisely
and know exactly what is expected of you.
e.g. Some examination papers will say things like: "Unless otherwise indicated candidates should answer to 2 decimal places". Remember this as you will lose a mark by giving an answer as 2.34567834899 rather than rounding it to 2.35. If no indication on rounding is given, ensure that you round your answers to the same degree of accuracy as other numbers which are provided in the question.
Also, make sure that you know how many questions you
have to attempt and how long you've got to answer them.
When you open the paper, do you ignore what's in it and steadily go from question
1 to 2 to 3 turning the pages as you go? Or do you find a question which you
know very well and do that first to build your confidence. It's entirely up
to you. I've found that the best thing to do is to very quickly scan
through all the questions - you'll see the ones you know well giving
you confidence, but this will give you an overall view of the whole exam paper
and will help in managing your time. Then wade your way through the questions
in sequence leaving out any that you don't like the look of until later.
DURING THE EXAM
Always check your work. Sometimes you can end
up with silly errors and not realise it unless you check that your calculations
are correct and that the answer is realistic. Statistics questions are notorious
for containing calculation errors as there are normally quite a few numbers
involved which need punching into your calculator. It's very easy to miss pressing
a key on your calculator which can result in silly answers like saying that
the distance from the Earth to the Sun is 14 Km
or quoting an average age as 230!
Always read each question thoroughly. Don't just
think "I know what this is all about" and trample through the question
in your hob nailed boots - as you're very likely to come unstuck or make silly
mistakes.
If you do a bit of maths before you start the exam it will be a great help,
even though not all questions will have the same number of marks, it is a good
idea to work out approximately how long you
have to answer each question. E.g a 1 hour 45 minute exam with 19 questions
allows about 5 minutes per question - so the last thing you want to do is linger
for ages on a tricky question when there are others you could be answering and
getting lots of marks for.
Always write down your method of obtaining answers
- put down all thoughts you think are relevant. Correct answers do not always
attract full marks - On a question worth 6 marks, even if your final answer
is wrong it's still possible to get 5 out of 6 marks for showing your method!
Be wary of rushing through the questions you believe you know well, as a simple
calculation error can throw you into confusion and dent your confidence. In
particular double check figures calculated when
drawing graphs and re-read the question to make sure you are not drawing the
graph of y = 2x rather than x =2y!
Always check the question for Units (minutes, Kilometers
etc.) and make sure that you use the correct units in your answer - remember
to perform unit conversions if necessary. Also remember that answers in £ are
always to 2 decimal places!
When calculating with minus numbers always show
your working e.g. 2 - (-7) = 2 + 7 etc. Even experienced mathematicians make
mistakes by missing minuses - make sure you don't.
Whenever you see a right-angled triangle in a diagram,
no matter what the wording of the question, immediately think tan, sin, cos
and Pythagoras. Then read the question properly and use these tools to get the
answer.
When "Diagrams not to Scale" or something similar
is seen next to a diagram - this means that you are expected to calculate the
answer and not measure the lines with a ruler or try to estimate.
If you can't see how to do any part of a question, miss
it out, but leave a gap in your answer book in case you can finish it
later. If you are still stuck and time is getting short, then try guessing -
you may get lucky.
