What Does AS, IB & AFP (GCSE) Mean?

AS is Advanced Subsidiary level followed by A-level. Those are usually for ages 16-18. IB is International Baccalaureate which is also the same ages. GCSE is for ages 14-16. I am doing my A-levels after completing AS so e-mail if you have any more questions. For AS, you usually do 4 subjects but for IB, you do 6.
