Eduqas A-Level Biology Maths Worked Solutions
Eduqas A-Level Biology Maths Worked Solutions
Complete, step-by-step worked solutions to every maths question in the Eduqas A-Level Biology past papers – written as clear teaching scripts by a Chartered Biologist and experienced A-Level examiner. The perfect companion for mastering the calculation questions that students most often drop marks on.
At least 10% of the marks in Eduqas A-Level Biology (A410QS) come from mathematical skills, and these are the questions students drop most often – not because the biology is hard, but because the method is never shown in full. Mark schemes give the answer and a couple of terse marking points; they rarely show you how to get there. This pack closes that gap.
Every calculation question from the Eduqas A-Level Biology (A410QS) past papers is worked through as a teaching script: the reasoning, the units, the rounding, and the exact point at which each mark is earned. It covers the full spread of the board’s examinable maths – magnification and scale bars, percentage change, rates, log scales, the Student’s t-test, the chi-squared test and the correlation coefficient, Hardy-Weinberg and Simpson’s index of diversity.
What’s inside
- Step-by-step worked solutions to every maths question in the Eduqas A-Level Biology (A410QS) past papers
- Each solution written as a teaching script – not just the final answer, but how to reach it
- Partial-credit notes showing exactly where each mark is earned
- Common-mistake warnings flagging the errors examiners see most
- Full coverage of the board’s maths skills, including the Student’s t-test, the chi-squared test and the correlation coefficient
- Guidance on choosing the right statistical test and stating a valid conclusion against the critical value

A worked solution, in full
Here is the kind of question students most often lose marks on, worked exactly as it appears in the pack.
Q. A bacterial population is plotted on a log10 scale. At 8 hours the graph reads log10(number of cells) = 2.85. Calculate the number of cells. (2 marks)
10x key: 102.85 = 707.9…Examiner note: the commonest error is doing 2.85 × 10 – that scores zero. Every log-scale question in the pack flags this trap.
How to use it
Work each past-paper calculation yourself first, then check your method – not just your answer – against the worked script. Because every step is shown, you can see precisely where a method broke down: a missed unit conversion, the wrong denominator in a percentage change, or the wrong statistical test for the data. The same handful of maths skills recur across the papers, so a few focused hours removes a predictable, repeated source of lost marks before the exam.
Who it’s for
Eduqas A-Level Biology (A410QS) students in Year 12 and Year 13, and tutors or teachers who want ready-made, mark-scheme-accurate model solutions to teach or set from.
