Understanding the Edexcel Papers

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.

The Three Papers at a Glance

	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.

Foundation vs Higher Tier

Edexcel offers two tiers. You sit all three papers at the same tier — you cannot mix and match.

Foundation Tier (Grades 1–5)

Questions start at grade 1 difficulty and work up to grade 5.
Some questions at the top of the paper overlap with the easier Higher questions.
The maximum grade available is a grade 5.

Higher Tier (Grades 4–9)

Questions start at approximately grade 4 difficulty and work up to grade 9.
There is an overlap zone around grades 4 and 5.
The minimum grade awarded is a grade 4; below that threshold you receive a grade 3 (an "allowed" grade) or U (ungraded).

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.

Time Per Mark

Each paper gives you 80 marks in 90 minutes:

90 minutes ÷ 80 marks ≈ 1 minute 7 seconds per mark

This means:

A 1-mark question should take roughly 1 minute.
A 4-mark question should take roughly 4–5 minutes.
A 5-mark question should take roughly 5–6 minutes.

Keep this ratio in mind as you practise. If you spend 8 minutes on a 2-mark question, you are over-investing time.

How Questions Are Ordered

Questions within each paper are arranged roughly in order of difficulty:

The first few questions are the most accessible.
Difficulty increases gradually through the paper.
The final questions are the most demanding for that tier.

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.

What Is on the Formula Sheet

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.

Formulae Provided (Both Tiers)

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

Additional Formulae Provided (Higher Tier)

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 − 2bc cos A	Non-right-angled triangle problems
Area of triangle = ½ab sin C	Triangle area using two sides and included angle

Formulae You MUST Memorise

These are not on the formula sheet and you need to know them from memory:

Circumference of a circle = πd = 2πr
Area of a circle = πr²
Pythagoras' theorem: a² + b² = c²
Trigonometric ratios: sin, cos, tan (SOH CAH TOA)
Area of a triangle = ½ × base × height
Speed = distance ÷ time
Density = mass ÷ volume
Pressure = force ÷ area
Percentage change = (change ÷ original) × 100
Probability rules

How Grade Boundaries Work

After every exam series, Edexcel sets grade boundaries based on the difficulty of that particular set of papers.

Grade boundaries are not fixed — they change every year.
They are set after the exams, taking into account how all students performed.
Typically, for Higher tier, a grade 9 might require around 70–80% of the total 240 marks, while a grade 4 might need around 15–25%.
For Foundation tier, a grade 5 might require around 60–70%, while a grade 1 might need around 10–15%.

These are rough guides — check the most recent published grade boundaries on the Edexcel website for current figures.

What This Means for You

You do not need to answer every question correctly to get a top grade.
On Higher, getting grade 7 might mean correctly answering around 50–60% of marks.
Focus on securing marks you can definitely get before tackling the hardest questions.

The Question Paper Itself

Front Cover Information

The front cover tells you:

Total number of marks for the paper.
How long you have.
How many questions there are.
Reminders about showing working and checking answers.

Answer Space

Most questions provide lined answer space directly below the question.
Diagrams may be printed with a note: "Diagram NOT accurately drawn" — never measure from these.
If you need extra space, use the blank pages at the back and clearly label which question you are answering.

Question Numbering

Questions are numbered sequentially (1, 2, 3…).
Sub-parts are labelled (a), (b), (c) etc.
The marks for each part are shown in brackets on the right: (2 marks), (3 marks), etc.

Practice Problem

Example: 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.

Key Reminders

Every paper is 80 marks, 90 minutes.
You get roughly 1 minute per mark — pace yourself accordingly.
Familiarise yourself with the formula sheet so you can find formulae quickly.
Know which formulae are NOT provided and memorise them.
Questions go from easier to harder — secure the early marks.
Grade boundaries vary — aim for a comfortable margin above your target grade.
