Am I doing the right A levels to get onto a history/modern language course?

When i chose my a levels i was unsure of what i wanted to study at University but i recently found a course that i am really interested in and would like to study. I am unsure however of whether i have chosen the right subjects in order to do this course. I study History, english lit, biology and chemistry at as level and I intend to drop biology at the end of the year. The course I have seen is History combined with a modern language that allows you to study abroad for 1 year of the course. I have always loved history, I enjoyed languages at GCSE and i really want to travel. The course I originally saw was at Oxford and said an a level in the language chosen was not required for some languages such as Italian and Greek which are the ones I would like to study (I have not decided which one yet). Obviously Oxford would be very difficult to get in to so I have checked and this course is available at other universities. Would i be able to get into this course however without a language? I studied Spanish at GCSE and enjoyed it very much, getting full UMS in the whole of the course. The only reason I didn't take it at a level was because I would be more interested in learning a different language such as Italian, but this was not available at my college. I was thinking of maybe picking up Spanish next year at AS level, but I don't know if that would make a difference if it is not the language I want to study. Any advice/ suggestions? Thanks
