Examiners estimate that candidates who show
working out get 10% more marks than those who don’t.
![Page 3: The key to success in GCSE maths. Examiners estimate that candidates who show working out get 10% more marks than those who don’t](https://reader030.vdocument.in/reader030/viewer/2022032517/56649cae5503460f94970f05/html5/thumbnails/3.jpg)
Remember every mark counts.
There is one mark difference
between Grade C and Grade D

Bring your own
scientific calculator to
maths lessons and learn how to
use it.

Make sure that you have all of the equipment
you need

Don’t give up. Keep
going. Use any spare
time to check
answers.

Show as much working out as
you can.

Do the working out the way you
want to do it.

If you are spending a lot of time
on a question
leave it and come back to it later.

If you have worked out
two answers cross out
the one that you think is
wrong.

Don’t rush when answering
questions. Take your time.

Read the scales on graphs
very carefully.

If you can work out the answer in two ways try both ways and check
that the answers are the same.
![Page 22: The key to success in GCSE maths. Examiners estimate that candidates who show working out get 10% more marks than those who don’t](https://reader030.vdocument.in/reader030/viewer/2022032517/56649cae5503460f94970f05/html5/thumbnails/22.jpg)
Remember that the answer to a
probability question must be
a fraction, a decimal or a percentage
![Page 23: The key to success in GCSE maths. Examiners estimate that candidates who show working out get 10% more marks than those who don’t](https://reader030.vdocument.in/reader030/viewer/2022032517/56649cae5503460f94970f05/html5/thumbnails/23.jpg)
Remember to put two figures after the decimal point when the answer
is in pounds.e.g. £2.30 not
£2.3

When multiplying out a bracket remember to
multiply everything in the
bracket.2(3a – 4) = 6a - 8
![Page 25: The key to success in GCSE maths. Examiners estimate that candidates who show working out get 10% more marks than those who don’t](https://reader030.vdocument.in/reader030/viewer/2022032517/56649cae5503460f94970f05/html5/thumbnails/25.jpg)
When you round a number
write down the full answer first.
22.455 = 22.5 to 1d.p.

Don’t assume anything about diagrams. Use
only the information you are given or can
work out.

Check answers to calculations
by estimating what the answer
should be.

Check to see if the answer needs to be written to a certain number
of decimal places or significant
figures.

Unless you are estimating an answer, don’t
round numbers part way through
a calculation

Remember that your calculator
doesn’t understand hours
and minutes. Don’t use a
calculator for time questions

Try not to leave any questions
unanswered. Make an
attempt you may get some
marks.
