How to get an A* in A-Level Maths
What does getting a A* in A-Level Maths take?
An A* in A-Level Maths requires ~90% across three papers. The defining skill is algebraic speed plus mechanics/statistics fluency under time. Top-band students drill the pure-maths algebra (proof, partial fractions, parametric, vectors in 3D), nail mechanics modelling, and practise Statistics hypothesis tests until reading + executing a question takes under 8 minutes per 8-mark question.
What grade-A* students do differently
- 1
Treat Pure as the foundation, not a topic
Algebra mistakes in Pure cascade into Mechanics and Statistics. Build Pure algebra speed to the point that a 4-mark differentiation or 6-mark partial fractions takes <4 minutes.
- 2
Drill the 8-mark synoptic questions
Questions that combine two topics (e.g., calculus + vectors, kinematics + integration) are where boards differentiate the A* from the A. Practise them weekly from October of Year 13.
- 3
Master modelling assumptions in Mechanics
Examiners reward students who state the modelling assumption (light inextensible string, particle, smooth surface) before solving. 1-2 marks per question are often earned by stating the assumption explicitly.
- 4
Practise hypothesis testing under time
Statistics hypothesis tests (binomial, normal) follow a strict template: hypotheses, test statistic, p-value or critical region, conclusion in context. Drill the template; do not improvise wording.
- 5
Build an Error Log + redo every paper twice
Sit a paper; mark it; redo errors; redo the entire paper 4-6 weeks later. The second sit is where the A* habits set.
Where the marks are lost
Examiner reports for AQA 7357, Edexcel 9MA0 and OCR H240 highlight:
- Algebraic manipulation slips on partial fractions and binomial expansion (often -1 to -2 marks).
- Mechanics: forgetting to resolve forces in both directions for a particle on an incline.
- Statistics: writing 'reject H0' without the 'sufficient evidence at the 5% significance level' contextual conclusion.
- Vectors in 3D: dropping a component when computing magnitudes or scalar products.
Why A-Level Maths is harder than people expect
The step-up from GCSE Higher to A-Level is partly content (calculus, statistics in depth, mechanics) and partly pace. The exam pace is roughly 1 minute per mark on a 100-mark paper. Untimed practice is the most common reason strong students under-perform.
Frequently asked
- What percentage is an A* in A-Level Maths?
- Roughly 87–90% across all three papers in recent years for AQA, Edexcel and OCR. The boundary is confirmed by the awarding body each summer after marking.
- Should I do Further Maths to help with regular A-Level Maths?
- Further Maths students typically score higher on A-Level Maths because the synoptic skills (complex algebra, abstract reasoning) overlap. But it's not required for an A* in A-Level Maths alone.
- Which exam board is easiest for an A* in A-Level Maths?
- There is no consistently easier board — boundaries shift each year. Choose the board your school enters you for and use its published spec + past papers + examiner reports.

A-Level Maths glossary terms
- Chain ruleThe chain rule differentiates composite functions: if y = f(g(x)) then dy/dx = f'(g(x)) · g'(x). It appears across A-Level Maths and Further Maths whenever an outer function wraps an inner function — common examples are sin(2x), e^(3x²) and (1+x²)⁵. Without the chain rule, every composite differentiation drops marks; with it, the standard trick is to spot the inner function first.
- Integration by partsIntegration by parts is the integral analogue of the product rule: ∫ u dv/dx dx = uv − ∫ v du/dx dx. Use it whenever the integrand is a product of two functions where one becomes simpler under differentiation (typically polynomial × exponential, polynomial × trig, or x × log x). The LIATE rule helps pick u: Logarithm, Inverse trig, Algebraic, Trig, Exponential.
- Binomial expansionBinomial expansion expands (a + b)^n using (a + b)^n = Σ (n choose k) a^(n−k) b^k for positive integer n. For rational/negative n the expansion is an infinite series, valid only for |b/a| < 1. A-Level Maths examines both forms; Further Maths extends to approximations. Sloppy work with the validity condition is a high-frequency lost mark.
- Implicit differentiationImplicit differentiation differentiates equations where y is not isolated, e.g. x² + y² = 25. Treat y as a function of x and apply the chain rule whenever you differentiate a y term — d(y²)/dx becomes 2y · dy/dx. Used heavily for circles, ellipses and tangent/normal problems where rearranging to y = f(x) is impractical.
- Differential equationsA differential equation relates a function to its derivatives. A-Level Maths examines first-order separable equations (dy/dx = f(x)·g(y)), solved by separating variables and integrating both sides. Applications include exponential growth/decay (dN/dt = kN), Newton's law of cooling and rate-of-reaction models. Further Maths extends to second-order equations and integrating factors.
- Parametric equationsParametric equations express x and y separately as functions of a parameter t, e.g. x = cos(t), y = sin(t). They model curves that aren't conveniently expressed as y = f(x) — including circles, ellipses, and projectile paths. A-Level Maths uses the chain rule dy/dx = (dy/dt) / (dx/dt) to find gradients, and substitution to eliminate the parameter and recover the Cartesian equation.
- Vectors in 3DA-Level Maths extends vectors from 2D to 3D using the unit vectors i, j and k. Examinable skills: magnitude (|v| = √(x² + y² + z²)), addition/subtraction, scalar multiplication, the equation of a line r = a + λd, scalar (dot) product, and using the dot product to test perpendicularity (v · w = 0) or find angles between vectors.
- P-valueA p-value is the probability of observing test statistics at least as extreme as the one obtained, assuming the null hypothesis is true. A small p-value (typically below 0.05) is evidence against the null hypothesis. A-Level Maths examines p-values for binomial hypothesis tests and normal hypothesis tests. A p-value alone is not a probability that the null is true — that's a common interpretation slip examiners penalise.
