Before you start

Make sure you're comfortable with these topics first:

Method

  1. Work through the paper in order but do not get stuck: if a question resists after a minute or so, note your best attempt, move on, and come back if time allows, since every early mark is worth the same as a late one.
  2. Since there is no calculator, rely on efficient written methods (column addition, subtraction, short and long multiplication and division) and know times tables to 12 x 12 without hesitation, so basic steps do not eat into your time.
  3. For fractions, percentages and ratio without a calculator, use non-calculator-friendly routes: percentages built from 10%, 5% and 1%; fractions of an amount by dividing by the denominator then multiplying by the numerator; ratio by finding the value of one share first.
  4. Show every step of your working in the space provided, even when an answer is obvious, since method marks are awarded independently of the final answer mark.
  5. Estimate before and after a calculation, by rounding each number to 1 significant figure, to check the final answer is a sensible size.
  6. Budget your time roughly in proportion to the marks on offer, so the longest, highest-mark question near the end gets proper time rather than being rushed.
  7. In the last few minutes, check every answer box has something written in it, and re-read each question to confirm the answer matches exactly what was asked, including any units or rounding instruction.

Worked example

A school tuck shop buys 60 chocolate bars for 45 pounds in total. It sells every bar for 95p. Work out the total profit the tuck shop makes once all 60 bars are sold.

  1. Find the total revenue from selling all the bars: 60 x 95p = 5700p, which is 57 pounds.
  2. Recall the total cost, which is already given as 45 pounds.
  3. Subtract the cost from the revenue to find the profit: 57 - 45 = 12.
  4. So the tuck shop makes 12 pounds profit.
