Knowing exactly what you are walking into is the first step to exam success. This lesson breaks down the structure of the Edexcel GCSE Mathematics (1MA1) examination so that nothing on exam day comes as a surprise.
| Paper 1 | Paper 2 | Paper 3 | |
|---|---|---|---|
| Calculator? | Non-calculator | Calculator allowed | Calculator allowed |
| Duration | 1 hour 30 minutes | 1 hour 30 minutes | 1 hour 30 minutes |
| Total marks | 80 | 80 | 80 |
| Tiers | Foundation / Higher | Foundation / Higher | Foundation / Higher |
| Weighting | 33⅓% | 33⅓% | 33⅓% |
Your final grade is based on a total of 240 marks across all three papers.
Edexcel offers two tiers. You sit all three papers at the same tier — you cannot mix and match.
Key decision: Choosing the right tier is important. If you are consistently scoring above 60% on Higher practice papers, Higher is probably the right call. If you are struggling to reach 30% on Higher papers, Foundation may allow you to maximise your marks on questions you can access.
Each paper gives you 80 marks in 90 minutes:
90 minutes ÷80 marks ≈1 minute 7 seconds per mark
This means:
Keep this ratio in mind as you practise. If you spend 8 minutes on a 2-mark question, you are over-investing time.
Questions within each paper are arranged roughly in order of difficulty:
On Foundation, the last questions are around grade 5 standard. On Higher, the last questions are grade 8–9 standard.
Tip: Do not assume the very first questions are trivial. Read them carefully — examiners sometimes test whether students rush familiar-looking topics.
Both tiers receive a formula sheet at the front of the exam paper. You do not need to memorise these — but you do need to know how and when to use them.
| Formula | When to use it |
|---|---|
| Area of trapezium = ½(a + b)h | Any trapezium area question |
| Volume of prism = area of cross-section × length | Prism volume calculations |
| Formula | When to use it |
|---|---|
| Quadratic formula: x=(−b±b2−4ac)/2a | Solving quadratics that do not factorise neatly |
| Cone curved surface area =πrl | Surface area of cones |
| Cone volume = ⅓πr2h | Volume of cones |
| Sphere surface area =4πr2 | Surface area of spheres |
| Sphere volume =(4/3)πr3 | Volume of spheres |
| Sine rule: a/sin A = b/sin B = c/sin C | Non-right-angled triangle problems |
| Cosine rule: a2=b2+c2−2bccosA | Non-right-angled triangle problems |
| Area of triangle = ½ab sin C | Triangle area using two sides and included angle |
These are not on the formula sheet and you need to know them from memory:
After every exam series, Edexcel sets grade boundaries based on the difficulty of that particular set of papers.
These are rough guides — check the most recent published grade boundaries on the Edexcel website for current figures.
The front cover tells you:
The table below shows one student's marks across three Edexcel Higher papers.
| Paper | Mark | Out of |
|---|---|---|
| Paper 1 (Non-calculator) | 52 | 80 |
| Paper 2 (Calculator) | 61 | 80 |
| Paper 3 (Calculator) | 58 | 80 |
Total = 52 + 61 + 58 = 171 out of 240
Percentage =(171÷240)×100= 71.25%
If the grade 8 boundary is 168 and the grade 9 boundary is 192, this student achieves a grade 8.
Many students know the structure but do not train for the pacing until it is too late. Build the following two drills into your revision.
Take any past paper, cover the second half, and give yourself exactly 45 minutes to complete the first half. The first half of a Higher paper is typically grade 4–6 material; the first half of a Foundation paper is typically grade 1–3. If you cannot clear the first half in 45 minutes with full working shown, you will run out of time on the real paper. Repeat weekly until you finish with 3–5 minutes to spare.
Do only the last five or six questions of a past paper, with a 25-minute timer. These are the stretch questions — algebraic fractions, circle theorems, vectors, functions on Higher; compound percentages, Pythagoras, bounds on Foundation. Practising them in isolation, at pace, builds confidence when they appear at the end of the real paper.
| Feature | Paper 1 | Papers 2 & 3 |
|---|---|---|
| Surd and exact-form questions | Frequent — non-calculator | Rare |
| Long arithmetic (e.g. 8.74×3.215) | Avoided — numbers are "nice" | Common — calculator expected |
| Trigonometry | Exact values (e.g. sin30°=1/2) | Numerical answers to 3 s.f. |
| Algebraic proof | Common | Common |
| Standard form arithmetic | Both appear; simpler values on Paper 1 | Both appear |
| Compound interest over several years | Rare | Common |
| Cone / sphere volume calculations | Possible (answer in terms of π) | Common (decimal answer) |
A key consequence: Paper 1 questions often look harder but use cleaner numbers, while Paper 2/3 questions look easier but involve messier arithmetic. Train for both.
Question (5 marks, Paper 1 Higher): The table shows a student's target percentage for each paper of an Edexcel Higher series. Paper 1 target is 55%, Paper 2 target is 62%, Paper 3 target is 60%. Each paper is out of 80. Work out, as a single fraction in its simplest form, the total number of marks targeted as a fraction of 240.
Step 1: Paper 1 target marks =0.55×80=44. Step 2: Paper 2 target marks =0.62×80=49.6. Since marks are whole numbers, round up to 50 (typical convention for targets). Step 3: Paper 3 target marks =0.60×80=48. Step 4: Total targeted =44+50+48=142. Step 5: Fraction =240142=12071 (divide by 2).
Answer: 12071.
The mark scheme would award M1 for a correct percentage calculation on any one paper, M1 for summing three correct percentages, A1 for 142, M1 for forming a fraction out of 240, A1 for 12071 fully simplified.
| Command word | What it means on a structural question | Typical marks |
|---|---|---|
| Work out | Perform the calculation and state a number | 2–4 |
| Calculate | Same as "Work out"; may imply multi-step | 3–5 |
| Describe | Explain in words (e.g. describe the structure of the exam) | 2–3 |
| Compare | Give both similarities and differences | 3–4 |
| Explain why | A reason using mathematical language | 2 |
Exam-style question (3 marks): A student scored 48/80 on Paper 1, 55/80 on Paper 2 and 51/80 on Paper 3. Given that the grade 7 boundary is 154/240 and the grade 8 boundary is 180/240, state the student's grade and calculate how many more marks they would need to reach the next grade.
Grade 3–4 answer (scores M1 A0 A0 — 1 mark): "Total = 48 + 55 + 51 = 154. Grade 7." Missing the second part; no calculation of the gap.
Grade 5–6 answer (scores M1 A1 A1 — 3 marks): "Total marks =48+55+51=154. Since 154 is exactly on the grade 7 boundary, the student achieves grade 7. To reach grade 8 they would need 180−154=26 more marks."
Grade 7–9 answer (full marks with communication): "Total mark across three papers =48+55+51=154. The grade 7 boundary is 154/240, so the student has achieved grade 7 (just on the boundary). To reach grade 8, they require an additional 180−154=26 marks across the three papers, which is equivalent to 24026≈10.8% more of the total available. Practically, securing around 9 extra marks per paper would move them comfortably into grade 8 territory."
Notice how the grade 7–9 answer uses precise terminology ("boundary", "equivalent to", "comfortably into grade 8 territory") and communicates reasoning, not just arithmetic.
