To complete IGCSE, a student should clear a minimum of five subjects. Treamis expects students to register for the core subjects English, Mathematics & Sciences. They can also choose other subjects offered at Treamis. However, by clearing a minimum of seven subjects, the student can get the ICE award which is more prestigious than the standard IGCSE.

Assessment for Cambridge IGCSE includes written & oral tests and practical examinations. Treamis considers both examinations as well as coursework for assessing the students. The subject teacher sets and grades the coursework which is moderated by CAIE.
