i suggest english language, ive just done my A2 exam in it. the whole course has been really interesting and i highly recommend it. whatever you do, dont do the combined course as im told that it has no reputation for university so choose either lit or lang, not both. Good luck!!
literature all the way - but my classes havent necessarily been "fast" i think it sparks off great debates as well
and you are looking at the texts which have shaped our society
unless you have a particular desire to study language in detail and on its own
