Original post by knowledgecorruptzHaha, I get that question a lot. Philosophy's just...amazing! Debating issues, applying critical thought, learning about new ideas and approaches. Trust me, there's so much more to philosophy than most preconceive. It's not all pretentious expatiation and impenetrable ramblings; when you get to the heart of it, Philosophy has a lot to offer.
But I was originally planning on studying straight Economics at university - most probably for the same reason you have chosen your career path: money. But I soon realised that, banal as it may sound, money isn't everything. You're going to spend three whole years at university (and then the rest of your life in a related field!) so choose a subject you enjoy! Well, that's my opinion, anyway.
In terms of difficulty, A-Level are of course a little tougher than GCSEs, but it's nothing like what your teachers have most likely been telling you. Geography's pretty much the same as it is at GCSE. Economics Unit 1 is very easy, it's all about exam technique. Unit 2, I have no idea. I missed A LOT of lessons this year so I'll be teaching myself , probably starting this week. Further Maths is no way near as hard as people make out (especially not at AS). If you can pick up new concepts quickly, you'll have no trouble with AS Further Maths. A2 gets a lot trickier, I hear, though - so perhaps you should bear that in mind. Looking at the work most of my friends are doing, it appears I have a very light workload with my subjects. I'd definitely recommend them, but I'd suggest taking a fifth A-Level with them or finding yourself some serious extra-currics (like I did).
Hope that was of some use.
