Quantitative skills in business exam tips

Exam tips

• Check your percentage change calculations

  Always divide the difference by the original value, not the new value, and multiply by 100.

  Using the original value ensures the percentage reflects the change relative to the starting point, which is the correct approach for business calculations.

• Check your units and data

  Always verify that the figures you use are in the same units (e.g., all in £ or all in units sold) and that you have included every relevant data point before calculating.

  Mis‑aligned units or omitted data lead to incorrect averages, which can misinform business decisions.

• Show all calculations clearly

  Write out each step of the calculation, including units, to avoid errors and make it easier for the examiner to follow.

  Examiners can award full marks when they can see your working and understand your reasoning.

• Use the same denominator for both ratios

  Always divide the profit figure by the same revenue figure to keep the comparison consistent.

  This ensures the ratios are comparable and reduces calculation errors.

• Show your work clearly

  When calculating the average rate of return, write out the formula, plug in the numbers, and keep the units consistent. This helps examiners see your reasoning and reduces the chance of a careless error.

  Clear, step‑by‑step work demonstrates understanding and allows the examiner to award partial credit if a small mistake occurs.

• Show your working

  Always write out the formula and show each step of the calculation.

  Examiners can award marks for correct method even if the final figure is wrong, and it demonstrates clear understanding.

• Check axis units and scales

  Always note the units (e.g., £, units, %) and the scale increments on both axes before interpreting values.

  Incorrect units or scale assumptions can lead to wrong calculations and conclusions.

• Interpreting profitability ratios in exam answers

  State the ratio, calculate the percentage, then explain what the percentage tells you about the company's cost structure and profitability.

  Examiners look for clear calculation, correct interpretation and contextual relevance.

• Reading a cash flow forecast

  Check the timing of inflows and outflows, identify any periods of negative cash flow, and plan for financing or cost adjustments.

  Understanding the cash flow pattern helps you anticipate liquidity needs and make informed decisions about borrowing or cost control.

• Use the 4Ps to structure your analysis of marketing data

  When interpreting marketing data, first identify the Product, Price, Place and Promotion elements that the data relates to, then analyse how each element influences customer behaviour.

  The 4Ps framework helps students organise their thoughts, ensures all relevant aspects are considered, and leads to a clearer, more structured answer.
