My uncle ( admissions officer at Warwick) told me when I was applying that there's a hierarchy of subjects, which applies for nearly every degree. Some degrees obviously have certain subject requirements but it goes roughly like this.
1) Maths, Chemistry, Physics, Further Maths
2) Biology, Economics, Languages (Spanish, Chinese, German, Latin), Politics, Geography, Computing
3) History, IT, Psychology, English, Business Studies, French, Geology
4) Other subjects like Art, Sociology, R.E etc
Your subject choice looks very good, most degrees will be open to you if you do well
