I do English Literature and English Language separately and honestly I prefer English Language as it is technical and fascinating. English Literature requires analytical skills and you will be reading a lot of books and having to analyse them in detail. Ideally degrees that may require English Literature are an English degree, a Law degree or maybe a Philosophy, Politics degree etc. English Language is suited to English degrees, Psychology degrees and Law degrees. With English Language, you will analyse the meanings of texts and learn the change of language and the way we learn to read and write and speak.
Doing both at A Level combined is a good alternative if schools won't offer English Language on its own.
