The Test IGCSE is devided 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.
IGCSE allows the student to have numerous choices of tests; however, there are some subjects requiring every student to take including Mathematics and ESL that questions are not multiple choices but they require to fill in the written words. This needs accuracy of knowledge in each subject principle
