Hear me out - I got advice from someone who know's what they're talking about, and I've realised they were speaking sense at the time.
An older student at Uni, providing English tutoring, advised me to go for the Eng. Lit option over the Lang/Lit. combined subject my sixth form was offering. Her reasoning was this:
In Language, there is a lot more freedom to write unrestricted, that's a bonus. (A lot of people in my Lit. class now wanted to do English Lang. just because they were good at creative writing). However, a lot of it is learning
how to write [persuasively, essay-structure, etc.] This content is not viewed/respected as highly in the eyes of Universities compare to Lit:
In Lit., the exams assume you already have a good base when it comes to knowing
HOW to write, and is a lot more to do with analysis, evaluation and deeper meanings within literature. Therefore, here you are combining the skills that you'd have learned in Lang. and using them to make arguments about possible interpretations of the texts you are studying. In this way, Unis see this a more-demanding subject, and rightly-so reward Lit. students as opposed to Lang students.
In fact, when A-level timetables and classes were being finalised for our year, the school decided to drop the Lang/Lit subject and go for straight Lit - while a lot of my classmates complained, it was a hidden blessing in disguise, since we now all have developed analytical skills we may not otherwise have done in Lang. since we wouldn't have studied as many texts and looked for meanings and whatnot. On top of that, the Edexcel spec. has blessed us with a coursework component in Year 13, where we are allowed to choose
any two texts (plays, books, whatever takes your fancy) of any genre or form and compare them in a 3k essay. This helped compensate for the dissatisfied the creative writers
While for GCSE, many students find Lang the easier of the two, for Uni prospects,
Lit is the favoured one (Lit. is a 'facilitating' subject (subjects that are respected by Unis, e.g. sciences, maths, humanities, etc) so while it may be 'harder', it's definitely worth it if you can hack the reading
Hope I could be of help
Good luck with your choices
