Well, I was thinking of taking Maths, and I'm predicted A* at GCSE (aaahhhh results in 2 days) but I've heard so many stories of how difficult it is at A level, and combined with the new A* grade needing over 90% I wanted to take subjects I'm comfortable with. I'm really good at practical maths, like the normal arithmatics etc, but at things like surds etc, im not so sure. Therefore, I had hoped that economics would give me better analytical/essay based skills and Chemistry would demonstrate my ability in terms of maths because of all the calculating involved. Basically, I'm substituting maths with Chemistry and Economics so that if I did want to do an ACA course, I can prove my maths ability, because firms like Deloitte only want an A at GCSE and a 2:1 degree in any subject.
