Difference between IGCSE Combined Science and IGCSE Coordinated Science

About Award and Certification:

Although Coordinated science is treated as a single Science subject, students still study all three types of science (Physics, Chemistry, Biology) and will receive up to 2 certifications (2 IGCSE certificates with the same score).

For Combined Science, students can only receive 1 certificate and must study the same program with Coordinated Science but with less contents.

About curriculum content:

IGCSE Coordinated Science will go through the entire content of the Combined Science course plus some more topics in all 3 modules of Biology, Chemistry and Physics.

The Coordinated Science course offers a more comprehensive overview of the three sciences and is generally recommended for all students, especially individuals who wish to study science further.

The Combined Science course has less content and is designed for students who feel that science and Mathematics are not their strong points, so taking this course reduces the weight of the overall IGCSE program.

About assessment

One difference between IGCSE Combined Science and IGCSE Coordinated Science is in the assessment and examination process. In both courses, students can choose the Core or Extended level, but if you want to get above C or better then you should take the Extended course.

 

If students choose to study Core level, they will have to complete Paper 1 and Paper 3, but the assessment in Paper 3 of Coordinated Science will be longer and more difficult than in Combined Science.

 

As for the Extended level, students must complete Papers 2 and Paper 4, similar to Core, Paper 4 at Extended level of Coordinated Science will also be longer and more difficult than Combined Science.
