In many schools this means deciding between A Levels and the International Baccalaureate Diploma Programme, often referred to simply as the IB Diploma.
The IB Diploma is a two-year programme for students aged 16 to 19 and is widely regarded as one of the most academically challenging school qualifications in the world.
Unlike A Levels, where students typically specialise in three subjects, IB students continue studying six subjects across a broad range of disciplines.
This means they maintain strengths in languages, humanities, sciences and mathematics while still developing areas of particular interest.
