I'm in year 12 and do english literature and i'm finding it quite good and very much like GCSE, you focus alot on context rather than plot though. I got a B at GCSE and now I'm currently working at a C grade at Alevel. Once you know the books, quotes, context and background well and learn how to structure responses it becomes much easier. I'm aiming for an A this year.
Depending on what board your on depends on how you'll be assessed. We have some coursework and then 2 exams but they're closed exams so you need to learn all the quotes for the exam and make sure you know the books and poems really really well. The texts are alot more challenging though, for example we're studying Jane Eyre and its a very heavy read when you have to annotate and remember quotes.
