IGCSE - International General Certificate of Secondary Education

What are the benefits of the IGCSE?

-       Students can choose the subjects and the level of difficulty that they want to take (see Core and Extended Level).

-       Grade C in IGCSE English (both First Language and Second Language) satisfies the English proficiency requirements of a number of universities in the UK and other Anglophone countries.

-       Grade C in both IGCSE and O Level Mathematics satisfies the matriculation requirements of universities in the UK, many Anglophone countries and other countries across the world.

The test is divided into 2 different levels as follows:

1.     Core Level is the measurement of the student’s knowledge of a specific subject at a less in-depth level; the number of questions and time allocated for the test are less than those of the Extended Level. The grades that each student can earn are C, D, E, F and G.


2.     Extended Level is the compilation of the Core Curriculum and other specific materials; the grades that each student can possibly earn are A, B, C, D, E, F and G.

In Thailand, students can apply to write the IGCSE test at the British Council, which has adopted the University of Cambridge International Examination (CIE); each student has the option to select more than 5 subject tests, but only 5 subjects with a grade of A, B or C can be selected for submission to the Ministry of Education in Thailand in order to be recognized as being the equivalent of a Thai high school diploma.
