Although I don't and am not planning to do A Level Maths (I'm in Year 11), I'm doing Further Maths at the minute (early entry, did the GCSE last year and got an A*) and I've been told it's similar in difficulty to AS Maths, although I think there's less content. I used to enjoy Maths to an extent, but the difficulty change has made me absolutely despise it because I don't enjoy it ENOUGH to dedicate enough willpower to it. If you're someone who doesn't like Maths at GCSE, I wouldn't bother, particularly if you don't need it for your chosen career path.
