Make your markTop tips for showing your working You need to use a blue or black pen in the exam. You can use a pencil for diagrams. Start a new line of working for each new calculation. Don’t ever rub or scribble anything out or use Tippex. If you make a mistake put a neat line through your work and carry on – you might still get some marks for it. If you round an answer write down the degree of accuracy you have used. Write down your calculations - if it’s worth typing into your calculator it’s worth writing on the exam paper.

Q0 (1 mark) £100 + 17.5% = £100 + £17.50
= £117.50
£100 + 15% = £100 + £15
= £115
£117.50 – £115 = £2.50
Yes Sample answer 1 Sample answer 1

This student has written the correct conclusion but hasn’t shown any working. He gets no marks.
Make your markLet’s look at a grade D question :
Make your markLet’s look at a grade D question (3 marks) 100 x 1.175 = 117.5
So £100 plus 17.5% VAT would be £117.50
100 x 1.15 = 11.5
So £100 plus 15% VAT would be £115
This means that after the VAT reduction the item is £2.50 cheaper.
(2.5 ÷ 117.5) x 100% = 2.13% (2 d.p.)
Jamie is wrong… it is 2.13% cheaper. Sample answer 3 Sample answer 3
