The course is two years long, covers four modules and is divided into two parts- the Advanced Subsidiary Level (or AS Level) and the A2 Level.
A Level qualification will be achieved by those who finish both AS and A2 Level. Otherwise the AS Level is a qualification on its own.
Students usually need to take up minimum four papers at the AS Level and can drop the fourth subject for the A2 Level. However, some choose to continue with the fourth paper in their second year of study.
Students are free to choose from amongst a wide variety of subjects
