GCSE MATHEMATICS
HOW TO IMPROVE YOUR GRADE
THE EASY WAY
EQUIPMENT:
Most students bring all the correct equipment
(Pens, Pencils, Ruler, Angle measurer/protractor,
Calculator)
However there is a lot of evidence which shows they
simply don’t use it!
DIAGRAMS:
Almost all diagrams are NOT drawn to scale.
Many students ignore this fact.
They simply measure angles and lines without
calculating them and consequently get no marks.
READ THE QUESTION:
It is recommended that you read the question TWICE.
There is plenty of time.
You can underline the important parts of a question if
you wish to
CALCULATORS
Make sure you can read a display that is in Standard
Form.
No credit is given for writing an answer as 1.6306.
Make sure your calculator is set in the DEG mode
FAMILIARISE YOURSELF WITH YOUR OWN
CALCULATOR
BRING IT TO SCHOOL EVERY DAY
DON’T RELY ON THE SCHOOLS CALCULATOR
WHICH MAY HAVE A DIFFERENT LOGIC SYSTEM TO
YOURS.
METHODS: Working out MUST be shown.
There are a lot of method marks available and it is
recommended that all relevant stages of working are
shown.
Incorrect answer and no working gains no marks
If correct working is shown and a careless error results
in an incorrect answer you could gain 4 out of 5 marks
available
MATHS SPECIFIC
ERRORS
PROBABILITY
A very large number of answers are still given as 1 in 2
or 5 out of 1O.
These are incorrect.
Answers should be decimals, fractions or percentages.
As a general rule if the question uses fractions then give
your answer as a fraction.
Reminder:
A probability answer cannot be greater than 1!
UNITS
You will have to give your own units for at least one
question.
Units of length, volume and area are frequently mixed up
by students.
Learn them.
Learn common Metric to Imperial conversions.
e g 1 kg = 2.2 lbs, 1 mile = 1.6 Km.
1 Gallon = 4.55 Litres etc.
Reminder: There are 52 weeks in a year.(Many students
use 50)
UNITS
Even if not asked to always write down units
at the end of a question
If a question contains mm and cm it
Is a good idea to convert all to the same
ACCURACY
Do not round answers off until the very last line of
working.
Use the calculator memory function and notation such
as 16.534…..
This is especially important in trigonometry questions.
(There is a significant difference between 23x1 .66 and
23x1.66666666)
If you are asked to measure a line and it measures
9.1cm use 9.1cm.
Do not assume that the line is supposed to be 9cm long.
TRIAL AND IMPROVEMENT
Usually there will be a table for you to write your
attempts in.
You do not need to fill in all the rows .
You must have at least one trial above and one trial
below the correct answer.
ANSWERS
If the question asks you to give the answer to 1dp,2sf or
in Standard form you will lose at least one mark every
time you fail to do so.
PERCENTAGE CHANGE
When asked for a sale price many students work out the
reduction correctly but then fail to take it away from the
original price losing at least 1 mark
FORMULA SHEETS
Make sure you know what is going to be given you on a
formula sheet.
Intermediate: Only the area of a trapezium and volume
of a prism are given.What formulae do you need to
know?
For borderline grade C students
It is also usually best to avoid the very hardest grade B topics
( eg Trigonometry and Simultaneous Equations )
These can take up a lot of revision time.
They actually aren't worth that many marks and
there are quicker and easier topics to revise first.
You need around 55% in the Intermediate GCSE Maths
exam paper to get a Maths GCSE grade C.
Don't just concentrate on the C grade questions.
Just as important are the earlier (and easier)
questions on the exam paper.
Make sure you have revised thoroughly these
easier grade D and grade E questions
These are worth 50% of the Intermediate GCSE Maths marks.
HIGHER PAPERS ONLY
HOW TO GET GRADE A:
Revise the easier questions
You need around 60% in the Higher Maths GCSE
exam to get a grade A.
Cover thoroughly the easier grade C and grade B
questions, as these cover the first 50%
of the Higher Maths GCSE exam
IT HAS BEEN ESTIMATED THAT BY FOLLOWING
THESE GUIDELINES STUDENTS CAN IMPROVE
THEIR MARKS BY UP TO 10°/o
THE AVERAGE DIFFERENCE BETWEEN A gradeD
AND A grade C IS ONLY 4%!!
