Exam content
The AQA GCSE Mathematics 8300 specification for 2027 covers six main topic areas:
Number covers the core calculation skills that appear throughout GCSE Maths. You need to be confident working with positive and negative numbers, fractions, decimals and percentages, as well as factors, multiples, prime numbers, powers and roots. You’ll also use standard form, estimation and rounding in both straightforward calculations and problem-solving contexts.
Accuracy is an important part of this topic. Make sure you can round to decimal places and significant figures, estimate answers to check whether they are sensible and work with error intervals and limits of accuracy where required. Percentage problems can include increases, decreases, reverse percentages and financial contexts, so being able to move confidently between fractions, decimals and percentages is essential.
A good habit is to sense-check every answer. Ask whether the size of the answer is reasonable, whether the units are correct and whether the question expects an exact or rounded value.
Higher Tier only
- Use the product rule for counting.
- Estimate powers and roots of any given positive number.
- Calculate with fractional indices.
- Calculate exactly with surds, simplify surd expressions and rationalise denominators.
- Convert recurring decimals to fractions and fractions to recurring decimals.
- Apply upper and lower bounds in calculations.
Algebra is about representing relationships and using them to solve problems. You need to be confident simplifying expressions, expanding and factorising, substituting into formulae, rearranging equations and solving equations and inequalities. You’ll also work with sequences, straight-line graphs, quadratic graphs and simultaneous equations.
Graphs are an important part of this topic. Make sure you can interpret gradients and intercepts, find equations of straight lines and use graphs to solve problems. You should also understand different types of sequences and be able to find nth-term rules where required.
Showing your working clearly is especially useful in Algebra. Keep each step organised and make substitutions and rearrangements easy to follow. Even if your final answer is incorrect, a correct method can still earn marks.
Algebra is particularly important at Higher Tier, where it makes up approximately 30% of the assessment.
Higher Tier only
- Simplify expressions involving algebraic fractions and carry out more advanced factorisation.
- Construct formal algebraic proofs.
- Understand inverse and composite functions.
- Identify perpendicular lines using their gradients.
- Complete the square and use it to find turning points.
- Recognise and interpret exponential and trigonometric graphs.
- Transform functions using translations and reflections.
- Calculate or estimate gradients and areas under non-linear graphs.
- Use the equation of a circle centred at the origin and find equations of tangents.
- Solve quadratic equations using completing the square and the quadratic formula.
- Solve simultaneous equations involving one linear and one quadratic equation.
- Use iteration to find approximate solutions.
- Solve quadratic inequalities and inequalities involving two variables.
- Find nth-term expressions for quadratic sequences.
This topic covers ratio, proportion, percentages and the way quantities change in relation to one another. You need to be able to simplify ratios, divide quantities in a given ratio and apply ratio to contexts such as recipes, maps, scale drawings and best-buy problems.
You’ll also work with direct and inverse proportion, percentage change, compound interest, growth and decay, and compound measures such as speed, density and pressure. Scale factors are important too, including relationships between lengths, areas and volumes.
When solving proportion problems, first identify how the quantities are related. Decide whether the relationship is direct or inverse, identify any constant of proportionality and then use that relationship to calculate the missing value.
Higher Tier only
- Construct and interpret equations describing direct and inverse proportion.
- Interpret the gradient at a point on a curve as an instantaneous rate of change.
- Use gradients of chords and tangents to work with average and instantaneous rates of change.
- Work with general iterative processes in growth and decay problems.
Geometry and measures covers shapes, angles, constructions, transformations and measurements. You need to understand angle rules, properties of polygons and quadrilaterals, congruence and similarity, bearings, plans and elevations, and transformations such as reflection, rotation, translation and enlargement.
You’ll also calculate perimeter, area, surface area and volume and work with circles, arcs and sectors. Pythagoras’ theorem and trigonometry are important for finding missing lengths and angles, and you should be comfortable applying them to unfamiliar diagrams and problems.
Annotating diagrams is one of the best habits you can develop. Mark known angles and equal lengths, label useful measurements and write down relevant geometrical facts before starting a calculation or proof.
Higher Tier only
- Use negative scale factors in enlargements.
- Describe the effects and invariance of combinations of transformations.
- Apply and prove the standard circle theorems.
- Use relationships between length, area and volume in similar figures.
- Apply Pythagoras and trigonometry in more complex two-dimensional and three-dimensional problems.
- Use the sine rule and cosine rule.
- Use vectors to construct geometrical arguments and proofs.
Probability is about measuring how likely events are and using information to predict outcomes. You need to understand the probability scale from 0 to 1, calculate theoretical and experimental probabilities and recognise when outcomes are mutually exclusive or exhaustive.
You’ll work with sample spaces, frequency trees, two-way tables, Venn diagrams and tree diagrams. Questions can involve independent and dependent events, so make sure you know when probabilities should be added and when they should be multiplied.
Always check that your final probability is between 0 and 1. When working with multi-stage events, organise the information carefully before calculating so that you do not miss possible outcomes.
Higher Tier only
- Calculate and interpret conditional probabilities using expected frequencies, two-way tables, tree diagrams and Venn diagrams.
Statistics is about collecting, representing, analysing and interpreting data. You need to understand different types of data and sampling, and be able to use tables, charts and graphs to present information clearly.
You’ll calculate and compare measures such as the mean, median, mode and range, and use quartiles, interquartile range and box plots to compare distributions. Scatter graphs are also important, including recognising positive and negative correlation, drawing lines of best fit and understanding that correlation does not necessarily mean causation.
When comparing data sets, support your statements with numerical evidence. Compare like with like, such as median with median or interquartile range with interquartile range, and explain what the difference means in the context of the question.
Higher Tier only
- Construct and interpret histograms with equal and unequal class intervals.
- Construct and interpret cumulative frequency graphs.
What to expect in the GCSE Mathematics exam 8300
AQA GCSE Maths has three papers. Each paper is 1 hour 30 minutes and 80 marks. Paper 1 is non-calculator, and Papers 2 and 3 allow a calculator. Foundation covers grades 1–5, Higher covers grades 4–9, and any topic can appear on any paper.
For the 2027 exams, you will be given a formulae sheet with every paper, so you do not need to memorise all the usual GCSE Maths formulae. You still need to recognise which formula to use, substitute values correctly and rearrange formulae where necessary. It still helps to recognise common ones quickly, because time pressure is real.
The biggest upgrade for Higher Tier is a method-first mindset. When a question feels hard, aim to earn method marks by setting something up correctly, even if you cannot finish. Write the equation you are using, show rearranging, and keep each step readable.
Paper 1 needs special practice because it is non-calculator. That does not mean it is mental maths only, it means you must be fluent with fractions, surds, exact values, and algebraic manipulation. Keep answers exact when the question expects it.
Finally, revise in exam patterns, not just topics. GCSE Maths questions often repeat structures like prove, show that, find values that satisfy, interpret a graph, and combine two topics. Practise spotting what the examiner is really testing, then choose a strong first step quickly.
