Hi,
I did Maths, Economics, History and Geography. I got As in all but Maths, in which I got a B. I wasn't best pleased about it but I knew deep down that I deserved it because I wasn't good enough and I didn't enjoy the subject. However, I worked hard and even though you might not want to do Maths (like I didn't want to), it really does pay off and as does the hard work. Anyway, a B is still a good grade (its the only way I can live with myself
) Having said that, English is also a very good subject to take.
I'll end with the same advice that was given to me:
Keep your subjects varied yet enjoyable, as they will enable you to choose many university courses and future careers. Think long-term (as you already are) and know that hard work always pays, even if you don't enjoy it at the time.
