GCSE vs IGCSE - what is the difference, and are IGCSEs harder?
IGCSEs (International GCSEs) are qualifications designed to be sat worldwide, offered mainly by Cambridge International and Pearson Edexcel. In the UK they are common in independent schools and popular with home educators, partly because some syllabuses are exam-only. Neither is officially harder: the differences are structural rather than a difficulty verdict, standards are broadly equivalent, and universities and employers treat the two the same.

What IGCSEs are, and who takes them
The IGCSE was created in the 1980s as an international version of the GCSE - a qualification international schools could teach anywhere in the world without a UK-specific curriculum. Today the main providers are Cambridge International (CAIE) and Pearson Edexcel with its International GCSE.
In the UK, three groups take them. Many independent schools use IGCSEs in some subjects by preference. International schools abroad use them as standard. And home educators and private candidates often choose them because several IGCSE syllabuses are assessed entirely by exam, with no coursework - which is a practical blessing when you have no school to supervise and mark coursework.
The differences that actually exist
Set the two side by side and the differences are structural, not a verdict on difficulty. IGCSEs often offer exam-only routes where the GCSE equivalent has assessed coursework. Content emphasis can differ - IGCSE syllabuses avoid UK-only framing, and in some subjects the topic mix is slightly different. Exam timetables and resit windows can differ too; some IGCSEs offer more than one sitting a year. Grading varies by syllabus: many IGCSEs are now graded 9–1 like reformed GCSEs, while some retain A*–G - the certificate says which.
One difference worth knowing for context: state schools in England overwhelmingly teach reformed GCSEs, because those are the qualifications that count in school performance measures. That is an administrative fact about schools, not a quality judgement about either qualification.
So are IGCSEs harder - or easier?
The honest answer is that there is no meaningful difficulty verdict, in either direction. You will find people online insisting each one is the soft option, which is itself a clue. Individual syllabuses differ in structure and emphasis, so a particular student might find a particular IGCSE syllabus more or less comfortable than its GCSE cousin - but the standards are broadly equivalent, and no sixth form, university or employer discounts one against the other.
If you are choosing between them as a private candidate, choose on the practical facts - coursework requirements, available exam centres, sitting dates - not on rumours of an easier ride. If you are at a school, the school has already chosen for you, and the choice will not disadvantage you either way.
What sixth forms and universities think
They treat them as the same thing, because for entry purposes they are: both are level 2 qualifications sitting in the same place in the framework. Entry requirements phrased as "GCSE grade 6 in maths" are read as covering the IGCSE equivalent as a matter of course. If a specific sixth form's wording leaves you unsure how it treats a specific grade or syllabus, ask them directly - but expect the answer to be a shrug and a yes.
