How to Get a Grade C, D or E in A-Level Maths

Honest advice for students who are finding A-Level maths tough — passing is more achievable than you think.

First, some reassurance

If you're struggling with A-Level maths, you are not alone. The jump from GCSE is genuinely significant — I've been tutoring this subject for over 15 years, and the number of students who sail through GCSE only to hit a wall in Year 12 never stops surprising people. It happens every year, to bright, hard-working students, and it doesn't mean you've made a mistake choosing the subject.

Let's look at what you actually need. A-Level maths is three papers, each two hours long, each worth 100 marks — 300 marks total. The grade boundaries from June 2024 tell a useful story:

  • Grade E: 73/300 (24%) on AQA, 56/300 (19%) on Edexcel
  • Grade D: 110/300 (37%) on AQA, 93/300 (31%) on Edexcel
  • Grade C: 147/300 (49%) on AQA, 130/300 (43%) on Edexcel

Read those numbers again. A pass — a grade E — requires less than a quarter of the marks on AQA, and less than a fifth on Edexcel. Even a grade C is roughly half marks. You don't need to be brilliant at everything. You need to be solid on enough topics to accumulate marks steadily across three papers.

The pass rate nationally is around 97%. A-Level maths is the most popular A-Level in the country, with over 100,000 entries in 2024, and almost everyone who sits it passes. That should tell you something: if you put in the work, passing is well within reach.

The real reason students struggle

In my experience, the most common reason students struggle at A-Level isn't that A-Level maths is impossibly hard. It's that their GCSE foundations have gaps. A-Level maths builds directly on GCSE Higher content, and if certain topics weren't properly consolidated, they'll cause problems almost immediately.

The GCSE topics that matter most for A-Level are:

  • Algebraic manipulation — expanding, factorising, simplifying, rearranging
  • Indices and surds — index laws, fractional and negative indices, simplifying surds
  • Quadratics — solving, completing the square, the discriminant
  • Graphs and functions — understanding transformations, sketching, gradient as rate of change
  • Coordinate geometry — equations of straight lines, midpoints, distances
  • Trigonometry — SOHCAHTOA, the sine and cosine rules, exact values

If any of those feel shaky, that's your starting point. Not the A-Level textbook — your GCSE textbook. There's no shame in going back. I've written a separate guide on how to revise for GCSE maths that covers these foundations in detail. The students who allow themselves to revisit GCSE content and fill those gaps are the ones who make the biggest progress. The ones who push on regardless tend to keep hitting the same walls.

The Year 12 trap

Here's a pattern I see every year. September feels manageable — some of the early A-Level content overlaps with GCSE, and the pace hasn't fully ramped up. Students think they're fine. Then, somewhere around October or November, the content jumps. Differentiation from first principles, logarithms, trigonometric identities. Suddenly it doesn't look like GCSE any more.

Students who were quietly coasting on their GCSE knowledge get caught out. And the problem is that Year 12 content is the foundation for Year 13. If you fall behind in Year 12, Year 13 becomes almost impossible — because new, harder material keeps coming, and it all relies on what came before.

If you're reading this in Year 12 and you're already feeling behind, the best thing you can do is get help now. Don't wait until January of Year 13. The earlier you address the gaps, the less catching up there is to do. If you're about to start Year 12, or you're in the early weeks, I've written a guide on how to prepare for Year 12 maths that can help you hit the ground running.

What to actually do: the textbook approach

My advice is the same whether you're aiming at a C, a D, or an E: open your textbook at chapter one and work through it in order. A-Level maths is cumulative. You can't do integration without differentiation. You can't do further trigonometry without basic trigonometry. The textbook is sequenced deliberately, and following that sequence is the most reliable way to build understanding.

Work through the exercises — not just the worked examples. The examples show you what to do; the exercises are where you actually learn. Roughly a third of the questions should feel comfortable, a third should feel manageable with effort, and a third should genuinely stretch you. That's the sweet spot.

For students aiming at grades D and E, you don't need to master every topic. Focus on the Year 12 content first — that's roughly the first half of your textbook. If you can get genuinely confident with that material, you'll be picking up marks on every paper, because exam questions span the full range of difficulty.

For a grade C, you'll need to push further into Year 13 content, but the same principle applies: work in order, don't skip, and make sure you understand each topic before moving on. And if you're on track for a C and feeling ambitious, have a look at my guide on how to get a grade B — the jump is very achievable with the right approach.

Resources that help

  • TLMaths on YouTube — clear, well-structured videos that follow the textbook topics closely. Excellent for when a concept isn't clicking from the textbook alone.
  • ExamSolutions — another strong YouTube channel with worked examples for virtually every A-Level maths topic.
  • Your Edexcel or AQA textbook — the single most important resource you own. Use it.

Don't neglect Statistics and Mechanics

About two-thirds of A-Level maths is Pure Mathematics — algebra, calculus, trigonometry, and so on. The remaining third is split between Statistics and Mechanics, at roughly 17% each. That's a combined 33% of your total marks.

I see this mistake constantly: students treat Statistics and Mechanics as afterthoughts. They spend all their revision time on Pure — which is understandable, because it's the biggest chunk — and then walk into Paper 3 unprepared. That's potentially 100 marks on the table, and leaving a third of them to chance is a strategy that costs grades.

Statistics topics like hypothesis testing and Mechanics topics like resolving forces and Newton's laws are learnable. They have clear methods. They reward practice. And for students aiming at C, D, or E, the earlier questions on Paper 3 are some of the most accessible marks in the whole exam.

Give these topics proper time. Work through the textbook chapters. Do the exercises. They're worth it.

Treat revision like the gym

The students who pass A-Level maths aren't the ones who do a 6-hour cramming session the weekend before the exam. They're the ones who did 20 to 30 minutes of practice most days, steadily, over months. Consistency beats intensity, every time.

Build a routine. Make it specific — sit down knowing which chapter you're working on. Don't just "revise maths" in a vague, unfocused way. And keep it sustainable. If you burn out in March, you won't have anything left for May and June when it actually matters. I've written a more detailed guide on how to revise for A-Level maths that covers building a revision plan from scratch.

A word about past papers

Save them. Past papers are a testing tool, not a learning tool. If you attempt a full past paper before you've covered the syllabus, you'll hit questions you can't answer, get demoralised, and learn nothing. That's not revision — it's just discouraging.

Use topic-specific questions as you work through the textbook. Most textbooks include exam-style questions at the end of each chapter, and those are ideal. Save full past papers for the final 8 to 10 weeks, when you've covered enough content to make them useful.

When you do past papers, mark them properly. Don't just check your final answers — read the mark schemes, understand where the marks are awarded, and go back to any topic where you dropped marks. That's where the real learning happens. You can find past papers from all the major exam boards at papers.bensmaths.co.uk.
