It's always annoyed me that I got a C grade Maths GCSE - the year after GCSE's were introduced. My crappy school would only put Set 1 in for the Higher exam, and because I was in set 2, I had to take the intermediate paper and the highest grade I could achieve was a C.
Is it possible to study for an IGCSE online? I would prefer the IGCSE to miss out the coursework element.
