Understanding the IGCSE Structure

The International General Certificate of Secondary Education (IGCSE) offers over 70 subjects, giving students the flexibility to design a curriculum suited to their interests.
Most students study between 5 to 7 subjects, covering a balance of core and optional areas.
Core IGCSE Subjects:
  • English Language
  • Mathematics
  • Science (Physics, Chemistry, Biology)
Optional Subjects:
  • Business Studies
  • Economics
  • Computer Science
  • Environmental Management
  • Geography or History
  • Second Languages (French, Spanish, Hindi, etc.)
If you are in an IGCSE homeschooling program, your subject selection can be even more flexible, allowing you to choose based on your pace, location, and available online tutors.

How to Choose the Right IGCSE Subjects

Selecting the right subjects requires balancing personal interest with practical considerations. Here’s a step-by-step guide to help you decide:

1️⃣ Identify Your Strengths and Interests

Ask yourself:
  • Which subjects do I enjoy studying?
  • Where do I perform best?
  • Do I prefer science, commerce, or humanities?
Homeschooling gives you extra freedom — you can choose subjects that align closely with your future aspirations.

2️⃣ Think About Your Career Goals

If you plan to study engineering, subjects like Maths, Physics, and ICT are essential. For business or economics, go with Mathematics, Business Studies, and Economics. If you aim for medicine, include Biology, Chemistry, and Physics. At Quest For Success, our academic advisors help IGCSE homeschooling students design subject combinations that match their university or career goals.

3️⃣ Maintain a Balance Between Core and Optional Subjects

A good IGCSE combination includes both compulsory and elective subjects.
For example:
