WJEC A-level Maths: the four units, grades and 2027 dates

WJEC A-level Maths: the specification

WJEC GCE AS and A level Mathematics is a Qualifications Wales regulated course, first taught in 2017, and it is not available to centres in England. WJEC's English brand Eduqas offers no A level Maths paper on the 2027 timetable, so this is the WJEC route for Welsh students. The AS can be taken alone, and counts for 40% of the full A level.

WJEC A-level Maths papers

Each paper has short and longer questions, some structured and some not, and some questions test more than one topic. In the applied papers the time can be split between the two sections however you like. You need a calculator with an iterative function and the ability to compute summary statistics and probabilities from standard distributions, and WJEC prints a formula booklet you can read about in our WJEC A-level Maths formula booklet guide. The dates are from WJEC's final summer 2027 timetable; see the WJEC A-level timetable 2027.

What each unit covers

• AS Unit 1: proof, algebra and functions, coordinate geometry, the binomial theorem, trigonometry, exponentials and logarithms, differentiation, integration and vectors.
• AS Unit 2: statistical sampling, data presentation, probability, distributions and hypothesis testing, then quantities and units, kinematics, forces and Newton's laws and vectors in mechanics.
• A2 Unit 3: more proof, algebra and functions, coordinate geometry, sequences and series, trigonometry, differentiation, integration and numerical methods.
• A2 Unit 4: probability, distributions and hypothesis testing, further trigonometry, differentiation and integration (including differential equations), and further kinematics and forces.

Across the A level, 50% of the marks are AO1 (using standard techniques), 25% AO2 (reasoning and communicating) and 25% AO3 (solving problems in context).

Worked examples in WJEC style

Pure: integration by parts

Find the integral of x eˣ. Take u = x and dv/dx = eˣ, so du/dx = 1 and v = eˣ:

Differentiate your answer to check: the product rule on e^x(x − 1) gives e^x(x − 1) + e^x = x e^x.

Statistics: a one-tailed binomial test

A manufacturer says 25% of its sweets are red. A sample of 20 has 9 red. Test at the 5% level whether the proportion is higher. H₀: p = 0.25, H₁: p > 0.25, and X ~ B(20, 0.25). The calculator gives:

The probability is below 5%, so reject H₀. At this significance level the sample suggests that more than a quarter of the sweets are red. Always finish with a sentence in the context of the question.

Mechanics: constant acceleration

A car brakes uniformly from 25 m/s to rest in 5 s. Use v = u + at with v = 0, u = 25 and t = 5, then find the distance with s = ½(u + v)t:

WJEC A-level Maths grades

Each unit is converted to a uniform mark, with the AS having 240 uniform marks and the A level 600. The unit grade is a lower case letter from a to e.

An A* needs an A overall (480 uniform marks) and at least 90% of the uniform marks for the A2 units, which is 324. See A-level grades explained.

Use the daily papers as short timed mocks for WJEC A-level Maths

Uni-Sine publishes a new free daily paper on each track: Algebra and Functions, Calculus, Statistics and Mechanics. It is a short timed mock: 8 questions worth 25 to 35 marks, marked instantly, with worked answers. It is not a full exam paper and it is not written by the exam board, so use it as a quick timed practice test alongside the board's own specimen and past papers.

• What it covers well: functions, logarithms, sequences, the binomial expansion, trigonometry, proof, differentiation and integration techniques, differential equations, hypothesis testing, distributions, SUVAT, projectiles and forces, which map onto all four units.
• What it does not cover: vectors and numerical methods, because none of the four tracks has a topic for them, and the mixed-topic questions that WJEC papers use to test more than one area at once.

Pick the track for the unit coming next, time one daily paper, then work a full WJEC unit paper once a week as the exam gets close.

Exam answers

Uni-Sine does not publish official answers, past paper answers or mark schemes from the exam board. The answers and a worked mark scheme for each daily paper come with that day's paper once it is marked, so you can see where every mark was won or lost.

Common mistakes in WJEC A-level Maths

• Revising the AS content only once. A2 Unit 3 builds directly on it.
• Not stating the conclusion in context after a hypothesis test.
• Forgetting the constant of integration in indefinite integrals.
• Spending too long on Section A of an applied paper. The time can be split but the marks are fixed.
• Leaving out units in mechanics answers.
