How Many Subjects Are There in IGCSE? Complete Subject List Explained

There are more than 70 subjects in Cambridge IGCSE, including around 30 different languages, and schools can mix and match them in almost any combination they like, with schools able to offer them in any combination. However, most students select only 70, typically between 5 and 10 subjects, which are selected from the major groups such as Languages, Sciences, Maths, Humanities and Creative subjects. Let's take a look at the IGCSE curriculum in simple terms to give you an idea of what it entails and how to choose the subjects for you.

What Is IGCSE?

IGCSE is an International General Certificate of Secondary Education. It is a study programme designed for students aged 14-16, typically completed in Grade 9 and Grade 10. IGCSE is developed and administered by Cambridge Assessment International Education, a part of the University of Cambridge, and is accepted in over 160 countries globally. 

Imagine IGCSE is a large buffet of subjects. You don't study all the subjects in the IGCSE Subjects List, and you don't eat all the foods at a buffet! You choose the ones that you like, are interested in, and have future plans for.

How Many Subjects Are There in IGCSE?

It is the first question that is asked by every student and parent. The easy answer is that:

• Total subjects offered: Over 70

• Languages included in that number: Around 30

• Subjects a school actually offers: Usually 15–25 (schools don't offer all 70, only a mix that suits their students)

• Subjects a student normally studies: 5 to 10

The IGCSE Curriculum may appear vast on paper, but no one student is studying all of it. You only select a few subjects that you can fit together like a team of your own.

IGCSE Subjects List by Group

Cambridge categorises all Cambridge IGCSE Subjects into five (or six) subject groups. This assists schools and students to select a balance rather than random selection of subjects.

This table is a fantastic overview of the full IGCSE Subjects List and is a testament to the fact that the IGCSE Curriculum is so popular with students who like variety because you can combine a science subject with an art subject, for instance!

Compulsory vs Optional Subjects in IGCSE Curriculum

Not all subjects are elective subjects. Most schools assign a few subjects as "must take" and the remainder are optional.

This balance ensures that the IGCSE Curriculum is well balanced so that all pupils are given excellent English and Maths skills and they are also allowed to pursue their interests in other subjects.

How Many Subjects Should a Student Choose?

The following is a basic guide that most Cambridge schools follow for IGCSE Courses:

The majority of students will complete between 7 and 10 IGCSE subjects as this is a good level of depth and breadth that is not overwhelming. If you are in doubt about the number of subjects to choose, 7 or 8 is generally a good and safe choice.

Tips for Making the Right IGCSE Subject Choices

The selection of subjects may seem confusing, here are some easy tips:

• Pick what you enjoy – These are subjects you will be studying for two years, so interest is important.

• Think about future studies – In case you're interested in becoming a doctor, Science subjects are more important.

• Balance is important – Don't choose just science or just arts, a combination will provide you with more options.

• Ask your teachers – They know which combinations work well together.

• Don't just chase easy subjects – Universities take an overall look at your performance, not on easy subjects.

Early planning of smart IGCSE Subject Choices is a great way to reduce stress later on, particularly when moving onto A Levels or IB.
