Wow! You're getting such mixed advice. I'd say (just to add to the confusion :P ) that the best option is: Maths, Further Maths, Economics, Physics and History/ Geography/ English lit./ a language. As you are doing both maths and further maths and are clearly a top student, you should probably take five subjects - some unis will only consider the maths/ further maths combination as one A level, besides you'll find maths really easy if you are doing further maths too. Economics is a pretty obvious one to do - I've seen a few people describe is as a bit of a 'doss' subject, load of rubbish. One of my friends just got an offer for economics at Cambridge (and I think she's also got one from LSE), she's taking economics, maths, further maths, possibly history or maybe german, and an extended project (I would definitely recommend this for your A2 year, universities apparently really like the EPQ). Physics is a very easy subject for any further mathematician with good logical thinking skills. And even if you're not that good at applying knowledge and using basic equations you can still do really well at it. And then an essay subject or a language is almost essential - economics is a weird mix of essays and maths from what I've heard, so being a bit more well-rounded would definitely be helpful. If you're not so good at English, a language is also a very facilitating subject - you can definitely link this into international business and stuff, and it may be useful if you want to do an internship abroad or just go on holiday!
