In general, the vast bulk of A level students are maths students who have been brave enough to make the jump from GCSE maths to the far more complex area of A level maths. In the case of maths, it is a huge subject, with many areas, indeed maths is a bit like space: there’s’ a lot of it. In general the problem is that the applications have not been fully understood: 3D trigonometry, for example, applies to telecommunications and weapons technology, the finer points of the calculus (integration and differentiation) apply to launching space ships and rockets etc and so on. Consequently the need is for a broader understanding of the context of the maths they are studying.
Otherwise there is a general demand for higher-level essay writing and other more general organisational skills.
It is not always understood that A level study is the same as university level other than the number of subjects at A level is fewer: 2 or 3 subjects over two years rather than 26 modules over 3 years. It is important at A level to develop the organisational skills that are required at university level.
Most A level students are bright by definition and once orientated are up and running after a few sessions.
All students have individual needs and we meet those needs according to their requirements etc etc.
