Hi
I have to disagree that universities prefer English Lit to Lang/Lit combined. The ultimate view of the university is that a student has the capability to interpret, analyse in detail and think independently. Your exam result will show this.
Although Language may not have as much reading, the content is quite technical as you are really getting an introduction into Linguistics and language development. You will look at speech, non-fiction texts and be analysing language and speech techniques as well as exploring research into language development. You would have covered some of these at GCSE.
Literature, as expected, will have a lot more reading of poetry, prose and drama. Depending on the exam board you may have specific themes as well e.g. struggle for identity or Literature from the Victorian period. You will be building on the literature techniques you acquired at GCSE.
The combination of the two can give a balanced insight into both areas. You will have fiction and non-fiction texts as well as poetry and drama. All I can say is that I don't think the university will be worried about whether it's combined or not. I've known people who have successfully made Oxbridge applications (even to study English) using either. Your choice of which to do is more about your GCSE grade, personal preference and commitment. Either one will not be easy.
Hope this helps.
