General

Question 1

Actively reflect on how a part of a question might refer to a previous part.

Answer 1

If they get you to prove something, there is a reason for it

Question 2

On the rare occasion they give you some piece of theory possibly required to solve on of these questions -

Answer 2

if you haven’t used the tip then reflect on your answer

Question 3

Marks for efficiency

Answer 3

Compare coefficients

Question 4

In MC, try using various answers to eliminate/find counterexamples

Answer 4

cant really just spot a pattern, must say why its true

Question 5

must justify

Answer 5

prove something

Question 6

Try all possibilities, eliminate all other possibilities, dont rush

Answer 6

sub in values for n, x, k, y, a, b…

Question 7

use what they have given you,

Answer 7

show thats: if havent got there, find the difference between yours and the answer

Question 8

Find pattern, sub in answers

Answer 8

Compare coefficients

Question 9

Find pattern writing solutions systematically

Answer 9

2/3 unknowns then compare coefficients and form simultaneous equations

Question 10

Think if there is a broader answer to the question

Answer 10

Draw sketch of whats happening as variables change

Question 11

Multiple choice:

Answer 11

try plugging in the available answers

Question 12

Compare coefficients

Answer 12

think what must happen to one

Question 13

Although one answer may be right,

Answer 13

are the others wrong

Question 14

Never that much work

Answer 14

Simplify, marks for efficiency

Question 15

Target show that questions

Answer 15

think about what they have given you and what you have got

Question 16

Show stuff, always do that extra bit

Answer 16

dont rush, or undersimplify

Question 17

Make sure answer suits all conditions, not just one

Answer 17

Always think about why they have given you certain details and their usefulness

Question 18

Use their hints, think about what they are asking

Answer 18

shows thats: think of relationship between your answer and what they want

Question 19

usually minimal work

Answer 19

compare coefficients

Question 20

Last few MC questions can be quite long and complex

Answer 20

worth doing though

Question 21

Can do show that from the LHS or the RHS if it says show that A is equal to B

Answer 21

Could be useful when factorizing as could expand and compare coefficients

Question 22

Write out answers and say what you are doing

Answer 22

Explain thought process
