Okay so top universities (Normally only the likes of Oxbridge, LSE etc) generally have listed subjects for A level on which are most practical for an academic standard. All of the A level subjects are split into Soft, Medium and Hard subjects or A,B and C with A being split into A1 and A2, So the different groups are A1, A2, B and C,
The A's are ones that are 'preferred' by Uni's (hard), The B's are ones that aren't great to have but will still be accepted (medium), The C's are the ones you want to avoid, these are regarded as next to 'useless' (I use this word with much emphasis) A levels to have (soft). Here's the official List...
Generally Suitable Science A-levels
Generally Suitable Arts A-levels
LIST B - Try to avoid these
Archaeology (Arch & Anth)
Art & Design (Architecture/History of Art)
Business Studies (Economics)
Design & Technology (Architecture)
Drama/Theatre Studies (Arts)
English Language (Arts)
Film Studies (Arts)
Government & Politics (Arts)
Media Studies (Arts)
LIST C AVOID at all costs - Unsuitable A-levels
Health & Social Care
Travel & Tourism
Now as you can see all your original subjects are in group 'A' however you are changing Maths to Politics which is in group 'B', University's sometimes say however, that it is okay to have ONLY 1 'medium' subject as long as the others are 'hard' subjects. Also the fact that Politics will go with History will be helpful.
In regards to university's if you were ever going to apply to Oxford you could do a subject call PPE.. Philosophy, Politics and Economics. If you are intersted in Politics this would be a great subject for you as it doesn't require any subjects by law but says a helpful subject is History which you have, Also having politics and economics may put you at some advantage. Also this course does not require mathematics but only says it would be useful but with just history you should be okay. However it will require AAA at A-level and I'm not sure on your A level capabilities...
In regards to Maths for economics courses, I'm afraid any top uni for economics does require a mathematics A-level, So if your are passionate about doing economics at a top university for economics or on a general academic standard Mathematics is essential, With top uni's asking for an A minimum and lower ones asking for a B minimum.
I hope this has helped you and aid your decisions! And please do not take my word for law but I believe I acquire a considerable amount of reliable advice.
EDIT: Oh and also btw Warwick University does require an A* in Maths GCSE for economics,politics and international studies if you don't take it at A-level, or have it as an As level (though I'm not sure on that last bit)
Also to clear things up St Andrews and Nottingham are rated 8th and 9th in the UK univeristy tables for economics However I am unsure if they require an A in maths, I would of thought they do though I am not sure..
