GCSE Maths Foundation Revision: How to Secure a Grade 4 or 5
The topics that earn the most marks on GCSE Maths Foundation papers, common mistakes to avoid, and a revision routine that turns practice into grades.
Where the marks actually are
On Foundation papers, roughly half the marks come from number and ratio work — fractions, percentages, ratio and proportion. These are also the most practisable topics: the question styles repeat year after year.
A grade 4 typically needs around 55–60% of the paper, and a grade 5 around 70%. That means you can skip nothing, but you should weight your revision towards the high-frequency topics below.
- Percentages and percentage change (appears on every paper)
- Ratio and proportion, including recipe and best-buy questions
- Area, perimeter and volume of standard shapes
- Averages and range from tables and charts
- Solving linear equations and substituting into formulas
Calculator vs non-calculator
Paper 1 is non-calculator, Papers 2 and 3 allow one. Practise the two modes separately: non-calculator papers reward fluent written methods (long multiplication, fraction arithmetic), while calculator papers reward knowing your machine — brackets, the fraction button, and rounding only at the final step.
The routine that beats cramming
Twenty focused minutes a day beats a three-hour Sunday session. Answer questions, mark them immediately, and read the explanation for every single one — including the ones you got right, because a lucky guess is a gap in disguise.
Keep a 'failed questions' list and re-test yourself on it weekly. When a topic stops appearing on that list, it's revised.
In the exam
Show your working even when you're confident — method marks rescue wrong answers. Attempt every question; a blank scores zero but a sensible start often earns a mark. And check units and rounding instructions before moving on: 'to 1 decimal place' ignored is a mark thrown away.
