How Many IGCSE Subjects Can You Take?

Trying to work out how many IGCSE subjects you should take can feel like a guessing game. Pick too few and you worry you'll fall short of a college offer. Pick too many and you're stretched across a dozen exams at once.

It doesn't help that everyone seems to give a different answer. So what's the actual number?

This guide clears it up. You'll find out the real minimums, the sweet spot most students aim for, the difference between core and elective subjects, and how to choose the IGCSE subjects that are right for you.

Key Takeaways

• Most schools ask you to take five or six IGCSE subjects, including English, Maths and Science.

• Most post-16 courses want a minimum of five IGCSEs at grade 4 (C) or above.

• Plenty of students take more - seven to ten subjects is common.

• Pass seven subjects across the five subject groups and you can earn the Cambridge ICE award.

• Your grades matter far more than which subjects you choose, so play to your strengths.

What is the IGCSE Qualification?

The IGCSE is a highly respected qualification that many schools - especially international, independent and some grammar schools - teach to students aged 14+.

It's the "international" equivalent of the British GCSE. Sixth-form colleges and universities treat both qualifications identically, including Oxbridge and the Russell Group.

In the UK, the most popular IGCSE courses come from two exam boards:  (opens in a new tab)

• Cambridge International Education (opens in a new tab)

• Edexcel (opens in a new tab)

There are minor differences in content, but both are equally well regarded.

How Many IGCSE Subjects Are Required?

Most schools require you to take five or six IGCSE subjects. Three of these are the core subjects: 

• English (Language and Literature)

• Maths 

• Science

If you want to carry on studying after 16, the number you'll need depends on where you're applying. Different schools, colleges and universities all set different requirements.

As a rule, most post-16 courses ask for a minimum of five IGCSEs at grade 4 (C) or above. English and Maths are always among them.

How Many IGCSE Subjects Should You Take?

There's a difference between the minimum you need and the number that makes your application stronger.

Cambridge offers 70 IGCSE subjects, including 30 languages, and schools can combine them freely. With that much choice, students rarely stop at five.

Most students take seven to ten IGCSE subjects in total. That's enough to show academic breadth without spreading yourself too thin.

Quality beats quantity, though. Strong grades in eight well-chosen subjects will always look better than middling grades across twelve.

Core vs Elective IGCSE Subjects

Schools ask students to study the same three core subjects:

• English (Language, and often Literature)

• Mathematics

• Science (as separate sciences or a combined award)

Outside the core, you're free to pick "elective" subjects from a wide range of areas, including STEM, the arts, humanities and PE.

This is where you get to shape your timetable around what you enjoy and where you're heading next.

The Five IGCSE Subject Groups - Cambridge International

Cambridge organises its subjects into five groups. Understanding them helps you build a balanced timetable, and it's how the Cambridge International Certificate of Education (ICE) award (opens in a new tab) is structured.

If you pass at least seven subjects spread across all five groups - including two languages from Group 1 and one subject from each of Groups 2 to 5 - you can be awarded the Cambridge ICE (International Certificate of Education). 

It's graded Pass, Merit or Distinction, and it looks great on a university application.

International IGCSE requirements

Different countries have slightly different IGCSE requirements. Some don't restrict students younger than 14 from starting, while others offer a one-year course instead of two.

In subjects like Maths and Science, high-achieving students can sit "Extended" or "Higher" papers to access the top grades. These tiers are available in the UK but not everywhere, so check what's on offer if you're moving between countries.

Beyond those differences, the IGCSE gives travelling students a lot of freedom. The qualification is taken in over 150 countries, so it's straightforward to transfer mid-study.

What Do Universities Look For?

As with GCSEs, your grades matter more than your specific subjects.

Higher education courses ask for a minimum of five IGCSEs at grade 4 (C) or above, usually including English and Maths.

Whether you're graded A*–G or 9–1 depends on your course and region. Universities don't distinguish between the two systems.

How To Choose Your Elective IGCSE Subjects

Universities and colleges rarely mind which electives you take. 

Some courses have specific preferences. For example, Medicine and Veterinary applications tend to favour more STEM subjects, but your grades count for far more than your subject list.

Here are three tips to help you choose well.

1. Choose subjects you enjoy. Play to your strengths. Your options should reflect your interests, because you'll always do better in subjects you actually like studying.

2. Think about your post-16 plans. Check whether your chosen college or university has any subject requirements. Most care more about A Level or IB grades, but IGCSE choices can still matter.

3. Research possible careers. Your IGCSE combination won’t limit your future options. Still, if you have an idea of the field you'd like to work in, it's worth checking whether it has any specific subject requirements. At the very least, it's an enjoyable bit of research that might motivate your revision.

Frequently Asked Questions

What is the minimum number of IGCSE subjects required? 

Most schools require five or six, and most post-16 courses ask for at least five IGCSEs at grade 4 (C) or above, including English and Maths.

How many IGCSE subjects do most students take? 

Seven to ten is the common range. High achievers sometimes take up to 14, but strong grades in fewer subjects beat weak grades in many.

Do universities care which IGCSE subjects you take? 

Mostly no - your grades matter far more. A few courses, like Medicine, prefer specific subjects such as the sciences. And other competitive courses, like Engineering at a top university will look more favourably on STEM subject combinations. 

If you know what you want to study in the future, take a look at entry requirements before choosing your IGCSE subject combination.
