I'd say English - it makes a very well-rounded set of AS levels, plus it's AMAZING (if you have the right exam board and get to do the same sort of stuff I did when I did it).
definately maths, having physics would look really good but like you say it may bog you down... don't just choose your subjects because they 'look good' though, choose them because you enjoy them..
To be honest For medicine you cant go far wrong with any of those (after chemistry and biology). The people i know who are doing medicine all do chemistry biology and maths. id personally go for physics but its entirely up to you. I think they'll be more fussed about the grade you get than the subject you get it in.

Im not sure Physics would bog you down any more than maths would. I don't do physics so i cant really tell but people seem to struggle as much if not more with maths at A level.
I'm agreeing with the general consensus of "do what you enjoy" though.
If you really hate maths I'm not sure you'd like physics as-level as that contains quite a lot of maths. Mostly just putting numbers into formulae, but it's maths nonetheless.
Between History and English, I don't really know what you'd prefer. Both are equally respected and would make good contrasting AS levels. If it was me I'd choose History as I prefer learning facts and writing waffly essays in not-so-perfect English. In English you have to be better at writing well, but there's less memorisation as you analyse stuff.
I agree with Tetra3, if you're not doing Maths/don't like Maths then you might not like Physics so much, and it will be a bit harder without Maths
If you don't mind Maths, most 'medics' usually take 'BCM', Biology, Chemistry, Maths, so I'd say do BCM + Geography, then you can pretty much go anywhere within your interests...
I am also in Year 11 and just chose my A-level choices
In the future I would like to study psychology, or maybe - more relevant to your choices - Biological Sciences.
For my A-levels I choose;
Biology Chemistry History English Literature
Biology & Chemistry are must-haves, History is well-respected, research based (as I'd expect is Geography) and English lit. is great for analysing materials and extensive essay writing - I, like you, don't like maths and so don't think I'd cope with AS physics, I can barely calculate resistance, lol.
In conclusion you are right to go with Biology and Chemistry, I then suggest a humanity and an art or two humaities to go with, all biology, Biological sciences (which Ecology comes under) courses I have looked at, require Biology/Chemistry and some "recommend" a third science or maths to atleast AS.
To be honest they'd rather you got AAA in something you like + Biology and Chemistry rather than AAC with the C in maths or physics, if you know what I mean!
As long as you pick those two to A2 and can justify your other choices (like I have) I see no reason why you couldn't study ecology at any university - be careful if you want to change to Biochemistry though, they normally want maths or physics!
