IGCSE vs GCSE Maths: which is harder?
How GCSE Maths compares with the two main IGCSE courses, Edexcel International GCSE (4MA1) and Cambridge IGCSE (0580): the papers, the calculator rules, the grades and the content, with example questions side by side.
The short answer
Neither is simply harder. At the top end, both IGCSEs go further: Higher 4MA1 and Extended 0580 include some calculus, and GCSE has none. But GCSE has a non-calculator paper, and Edexcel 4MA1 has none, so for some students GCSE feels harder.
The grades are on different scales too: GCSE and 4MA1 use 9 to 1, while Cambridge 0580 (this syllabus) uses A* to G. Choose by what your school offers and how you work best, not by reputation.
Side by side
| GCSE (Edexcel 1MA1) | Edexcel IGCSE (4MA1) | Cambridge IGCSE (0580) | |
|---|---|---|---|
| Papers | Three papers of 1 hour 30 minutes, 80 marks each, all at the same tier | Two papers of 2 hours, 100 marks each (50% each) | Core: Paper 1 and Paper 3, 1 hour 30 minutes and 80 marks each. Extended: Paper 2 and Paper 4, 2 hours and 100 marks each |
| Calculator | Paper 1 is non-calculator; a calculator is allowed on Papers 2 and 3 | A calculator may be used on both papers | Papers 1 and 2 are non-calculator; a scientific calculator is needed for Papers 3 and 4 |
| Grades | Foundation: grades 1 to 5. Higher: grades 4 to 9 (a 3 is allowed) | Foundation: grades 5 to 1. Higher: grades 9 to 4 (a 3 is allowed) | Core: grades C to G. Extended: grades A* to E |
| Calculus | None | Higher tier: differentiation, turning points and kinematics | Extended: differentiation, gradients and turning points |
| Exam series | May/June, and November (with entry restrictions) | January and June | June and November (and March in India) |

What students find hard
- Non-calculator work. GCSE puts a third of the marks on a non-calculator paper and 0580 half. 4MA1 allows a calculator throughout, which suits students who are slow with written arithmetic.
- Calculus at the top. Students aiming for the top grades in 4MA1 or 0580 meet differentiation, which GCSE leaves to A Level.
- Longer papers. IGCSE papers are 2 hours on the higher tiers, against 1 hour 30 minutes at GCSE, so stamina matters.
- Question style. Every board writes questions differently. Practising your own board's style is worth more than worrying about which board is harder.
This is our view from teaching these courses, not a statistic. We don't quote pass rates here: the exam boards publish their own results each year.
Try it: questions side by side
Each pair takes the same idea at two levels. Try both before you open the answers.
Without a calculator (GCSE Paper 1, 0580 Papers 1 and 2)
Without a calculator, work out 3/8 of 960.
Show the answer
Answer: 360
- 960 ÷ 8 = 120, and 120 × 3 = 360.
Calculator allowed (every 4MA1 paper)
Work out (4.72 + √30.25) ÷ 1.6. Give your answer correct to 3 significant figures.
Show the answer
Answer: 17.2
- 4.72 = 22.09 and √30.25 = 5.5, so the top is 27.59.
- 27.59 ÷ 1.6 = 17.24375…, which is 17.2 to 3 significant figures.
GCSE Higher (no calculus)
The line L passes through the point (2, 5) and is parallel to the line y = 3x − 2. Find an equation of L.
Show the answer
Answer: y = 3x − 1
- Parallel lines have the same gradient, 3.
- 5 = 3 × 2 + c gives c = −1, so y = 3x − 1.
4MA1 Higher and 0580 Extended (differentiation)
Find the gradient of the curve y = 2x3 − 5x at the point where x = 2.
Show the answer
Answer: 19
- dy/dx = 6x2 − 5.
- At x = 2: 6 × 4 − 5 = 19.

How to get ready
Whichever you take, the same habits work: secure your number and algebra skills, practise little and often, and use past papers from your own board in the final months.

Common questions
Is IGCSE Maths harder than GCSE Maths?
Not overall. The top tiers of both IGCSEs include differentiation, which GCSE does not, but GCSE has a non-calculator paper and Edexcel 4MA1 does not. Which feels harder depends on the student.
Do IGCSE and GCSE use the same grades?
Edexcel 4MA1 uses 9 to 1, like GCSE. Cambridge 0580 uses A* to G on the current syllabus: A* to E on Extended and C to G on Core.
Is IGCSE good preparation for A Level or IB maths?
Yes. The top tiers of both IGCSEs include some differentiation, which gives you a head start on calculus. Whatever you take, secure algebra matters most.
Can I practise both here?
Yes: the 4MA1 hub and the 0580 pages, and Pass GCSE Maths for the GCSE grade 4 basics.
