Higher Tier GCSE Maths preparation for AQA paper 2.

1. CALCULATE

2. PAPER 1
 Its all done now, don’t dwell on it too much
or celebrate yet.

4. PAPER 2…
 50% more marks
 33% more time
So
Therefore it is crucial in
determining your final grade.
 Can still assess content that was in paper 1!

10. TODAY
We are going to look through some examples which
are typical calculator problems.
There is no guarantee that these topics will come up
on paper 2. (Unlike Marty McFly we cannot travel to
the future!)
Other topics will come up
that do not appear in this
list- so revise EVERYTHING!

11. TIPS FOR OVER HALF TERM

Remember this is a calculator paper- so
you can use you calculator for every
question!

12. AVERAGES AND DATA HANDLING
 Higher Tier data handling is more likely to be based
on grouped and/or continuous data
 Cumulative Frequency, LQ, median, UQ etc along
with boxplots are common questions

13. AVERAGES - SKILLS

14. AVERAGES – EXAM QUESTION

15. ERROR BOUNDS
 Rounding to significant figures and decimal places
means that there is potential variation in the actual
value
 eg 1500 to 2sf could be anything between 1550 and
1450
 A possible method to ensure you have the upper or
lower bound of a calculation is to quickly calculate
all the possible options (in a systematic way) and
then identify the highest/lowest values

17. ERROR BOUNDS

18. REVERSE PERCENTAGES
 Reverse percentages are the questions that ask
what the ORIGINAL price was before a
sale/discount etc
 The key is to think about the calculation that would
have been done to achieve the value and then
undo it.
 Decimal multipliers are the only effective way of
consistently getting this right!

19. REVERSE PERCENTAGES
 Something that has been reduced by 25% would
have been multiplied by 0.75
 So to get the original just divide by 0.75

20. REVERSE PERCENTAGES

21. TRIAL AND IMPROVEMENT
 Trial and improvement should only be used on
questions that mention it specifically
 More than any other question, the majority of the
marks are for your working out, not you final answer
 Remember to give you answer to the right level of
precision as given in the question.

22. TRIAL AND IMPROVEMENT
 Layout is important!

23. TRIAL AND IMPROVEMENT
 Substitute in whole numbers (in this example).
 If the answer is smaller than you want use a larger
value
 Decide (and state) which values x must be between

24. TRIAL AND IMPROVEMENT

25. TRIGONOMETRY
 Soh Cah Toa – Only for right-angled triangles.
 Sine or Cosine Rule – Formulae given on the first
page of your exam.

26. SOH CAH TOA
 Remember to label the sides of the triangle using o
(opposite), a (adjacent) and h (hypotenuse).

27. SOH CAH TOA

28. SINE/COSINE RULE

29. SINE/COSINE RULE

30. SINE/COSINE RULE

31. DIRECT AND INVERSE PROPORTION
 Direct proportion – y is directly proportional to x ( y
α x ) means y = kx
 You must calculate the constant of proportionality k by
using the values of x and y given in the question
( y α x2 ) means y = kx2 or ( y α √x ) means y = k√x
 Inverse proportion – y is indirectly proportional to x (

32. DIRECT AND INVERSE PROPORTION

33. PROBABILITY TREES
 Remember to read the question carefully.
 Does it mention replacement?
 Are the events independent?
 To calculate probabilities of events, you must
multiply along the paths of the tree.
 You may then also need to add separate outcomes
together.
