When students reach the final four years of studying at BISL, they start their IGCSE and A Level programmes. The IGCSE is a two-year programme, culminating in final exams at the end of the second year.

During the IGCSE programme, students study six compulsory subjects:

  • English Literature,
  • English Language,
  • Mathematics,
  • Biology,
  • Chemistry, and
  • Physics.

In addition to these core subjects, students choose three more subjects from the subject groups that we create each year, tailoring their education to their interests and future aspirations.

Explore all the benefits of both IGCSE and A-Levels in our article, where we explain in detail what makes each programme unique and how they can help you achieve your academic and career goals.

A-Levels programme

For the final two years at school, and in preparation for our students’ entry to university, our Sixth Form students in Years 12 and 13 prepare for A Level examinations.

A Levels remain the gold standard for students who aspire to access universities around the world. A Levels are taken over two years: the first year is called an AS, or Advanced Subsidiary level. This is equivalent to half an A Level. The second year is called an Advanced level, or A2.

Students typically study four AS subjects in Year 12 and take three of these subjects through to A in Year 13.
