Thanks for the Advice guys; I've decided to drop Eng Lang and do History, so many thanks for the advice.
You say you don't need to do a Maths degree to become a Trader (alternatively a Quant which I know prefers a PHd (Something I'm considering)) what do most traders do? I doubt they'd simply do A-Levels.
I know it's easy, at GCSE Level, to underestimate the work load and difficulty of A-Levels but I definitely want to do 5, even if it means a sacrifice in terms of some Social time.
In regards to Further Maths, I want to do it as I want to go to Oxbridge, therefore doing Further Maths get's my further ahead and conveys ones skills in Maths (Especially if achieving A).
