A-level English Lit IssuesWatch
There is only a maximum of one actual comparative question for any AQA exam paper at A level so I'm not quite sure how you've got that impression really. There are questions where you have to split your time between two texts but not actually compare them directly. Look again would be my advice.
I've just done English Lit AS level and studying it was amazing. I sat two AQA A exams- one that consisted of an Othello extract and question, as well as a poetry question, and the other having an unseen extract and then a comparison question of The Great Gatsby and Wuthering Heights. Comparing really isn't that bad, as you are still analysing them separately, but then explaining whether they are similar are different for different themes/accounts. Honestly, it's my favourite subject and if you loved English GCSE then I wouldn't worry about it and just go for it!
