Academics
Overview
At TSI, Sixth Form students have the choice between two very different but equally challenging and rewarding pathways:
1. The A Level Programme (below)
2. The TSI Diploma Programme (click HERE for details)
The A Level Programme provides academic study in the students’ choice of 3 to 4 subjects, leading to internationally recognised qualifications (AS and A2). AS and A2 Level Examinations are widely recognised throughout the world for entrance into universities and colleges.
Building on the firm educational foundations established in the earlier Key Stages at the school, the curriculum in Years 12 and 13 provide our senior students with a challenging, relevant and varied course of study to prepare them for the demands that they will face in university and beyond.
