A-Level guide
Why does A-Level Maths feel so much harder than GCSE, and how can my child catch up?
Quick answer
A-Level Maths builds on the whole GCSE Higher content, then adds calculus, proof and unstructured problems. Students who were unsure of algebra at GCSE feel the jump most. The fix is to secure algebra in the first six to eight weeks of Year 12, practise regularly, and learn to set out full working.
Why does A-Level Maths feel so hard at first?
A-Level Maths feels hard because it assumes your child has already mastered GCSE, then moves much faster. Many strong GCSE students are surprised by how quickly Year 12 starts.
The Department for Education's A-Level Maths subject content says A-Level specifications "must build on the skills, knowledge and understanding set out in the whole GCSE subject content for mathematics". That means the whole Higher tier, including the hardest algebra, is treated as known.
It also says A-Level Maths "builds from GCSE level mathematics and introduces calculus and its applications". Calculus is new to most students, and it relies on confident algebra.
What is actually different between GCSE and A-Level Maths?
The biggest differences are speed, algebra and the type of question. Here is how they compare.
| GCSE Maths | A-Level Maths | |
|---|---|---|
| Questions | Often broken into small steps | Often one longer problem with little guidance |
| Algebra | One topic among many | Used in almost every question |
| New ideas | Builds slowly over years | Calculus, logarithms, proof and vectors in two years |
| Working | Answers often get most marks | Marks depend on clear, logical working |
| Applied maths | Some statistics | Full statistics and mechanics papers |
The A-Level specifications set out three "overarching themes": proof, problem solving and modelling. AQA's overarching themes page asks students to "construct extended arguments to solve problems presented in an unstructured form". In plain English, the exam often will not tell your child which method to use.
How is A-Level Maths assessed?
A-Level Maths is assessed by three exams at the end of Year 13. For example, the Pearson Edexcel specification (9MA0) has:
| Paper | Content | Length | Weight |
|---|---|---|---|
| Paper 1 | Pure Mathematics | 2 hours, 100 marks | 33.33% |
| Paper 2 | Pure Mathematics | 2 hours, 100 marks | 33.33% |
| Paper 3 | Statistics and Mechanics | 2 hours, 100 marks | 33.33% |
Two-thirds of the marks are pure maths, which is mostly algebra, functions, trigonometry and calculus. The statistics section also uses a "large data set" that students are expected to study before the exam. Edexcel says questions "assume knowledge and understanding of the data set". AQA and OCR have their own versions, so check which board your child's school uses.
Which skills cause the most trouble in Year 12?
In our experience, most Year 12 problems come from a small number of GCSE skills that were never fully secure. These are the ones we check first:
- Rearranging and simplifying expressions, especially with fractions and negative signs
- Indices and surds, including negative and fractional powers
- Factorising quadratics and completing the square
- Solving simultaneous equations, including one linear and one quadratic
- Straight-line graphs and the equation of a line
- Trigonometry beyond SOHCAHTOA, such as the sine and cosine rules
If your child got a grade 6 or 7 at GCSE, there are usually some gaps here. Even grade 8 and 9 students can be rusty after a long summer.
Why does a grade 7 or 8 student suddenly struggle?
Students who did well at GCSE can still struggle because GCSE rewarded getting the answer. A-Level rewards the method.
At GCSE, a student might reach the right answer with trial and error or a calculator. At A-Level, the same shortcut does not work, and examiners want to see each step. A student who skips lines of working often loses marks even when the final answer is close.
The other reason is volume. A-Level covers a lot of new content quickly. A student who falls behind for two or three weeks can find that every new lesson uses the topic they missed.
How can my child bridge the gap?
The best approach is to secure algebra early and practise little and often. Here is a simple plan for the first term.
Weeks 1 to 2: check the foundations
Do a short diagnostic test on the GCSE skills listed above. Many sixth forms give a summer bridging pack, so finish it if your child has not. Write down every topic that causes trouble.
Weeks 3 to 8: fix one gap at a time
Spend 20 to 30 minutes, three or four times a week, on the weakest skill. Use short, focused exercises rather than long sessions. Algebraic fractions, indices and quadratics are usually the priority.
Every week: keep up with new content
After each lesson, your child should redo one or two class examples without looking. If they cannot, that is the topic to ask about in the next lesson. Small questions asked early prevent big problems later.
From half-term: start exam-style practice
Use past questions on topics already covered, marked against the official mark scheme. This shows your child how marks are given for method, not just answers.
What habits help most in A-Level Maths?
The habits that help most are writing full working, checking answers and practising regularly. A few tips we give every Year 12 student:
- Write every step. One line per step makes mistakes easier to spot.
- Learn the formula booklet. Know what is in it and, just as important, what is not.
- Keep an error log. Note each mistake and its cause. Patterns soon appear.
- Do not wait for the mock. A weak topic in October will still be weak in June unless it is fixed.
Should my child drop A-Level Maths if they are struggling?
Not usually in the first few weeks. Many students struggle at first and then settle once their algebra is secure.
It is worth talking to the school if your child is still finding it very hard by the end of the first term, despite regular practice. Bear in mind that A-Level Maths is required or preferred for many science, engineering, economics and computing degrees. Check the course pages of the universities your child is considering before deciding.
How LCB can help
Our maths tutors start with the GCSE gaps that hold Year 12 students back, then move on to the A-Level content your child is learning in school. Lessons are in small groups of 3 to 5, with the same tutor every week, taught to your child's exam board.
Our founders studied at Imperial College London, and our tutors studied at top UK universities. Lessons run at our Barking centre or live online, and A-Level plans start at £72 a month with no contract. See our A-Level tutoring page and pricing for details.
The first step is a free 30-minute assessment, which will show exactly which skills need work. Book a free assessment and we will call you back within two hours during opening hours.
Strong Year 12 results also feed into university applications. Read our guide on how A-Level predicted grades are set.
Questions parents ask
- Is a grade 6 at GCSE enough to take A-Level Maths?
- Each sixth form sets its own entry requirement, so check the school's admissions page. In our experience, students starting from a 6 can succeed, but they usually need to work on algebra from the start.
- Should my child do work over the summer before Year 12?
- Yes, a little helps. Revising GCSE algebra, indices, surds and quadratics over the summer makes the first term much easier.
- How many hours a week should a Year 12 student spend on Maths outside lessons?
- There is no official figure, so ask the school what it expects. Regular short sessions through the week work better than one long session before a test.
- Is Further Maths much harder than A-Level Maths?
- Further Maths covers extra topics and moves faster, so it suits students who are already confident with A-Level Maths content. It is a separate A-Level.
