I can't speak for English language but for English literature, I had to remember A LOT of quotes. It depends on the exam board -- I was with Eduqas and my drama paper was closed book and it covered three plays: King Lear (Pretty sure it's on the curriculum now that you have to study a Shakespeare play so there's no escaping that!), The Duchess of Malfi and A Streetcar Named Desire. I really struggled with remember pages and pages of key quotes and I completely messed up that exam. My poetry paper was open book so I didn't need to memorise much there. Aside from quotes on the texts, there's also the element of critics where you'll be expected to memorise quotes from critics and incorporate them into your exams. There's also an unseen paper where you'll be provided with an unseen extract and a poem as well as quotes from critics so I didn't need to remember anything there.
As for coursework, I loved writing it! Again, it depends on your exam board and how teachers teach it but I had to write an essay comparing two characters from two different books and I really felt in my element. Sometimes they'll let you choose which books you want to use but I didn't get a choice. I didn't like the books I had to use initially (A Room with a View and Girl Meets Boy) but found that analysing them made me admire more because of all the little things you see the authors do. No need to memorise quotes or anything as you'll probably have months to work on it and you'll probably have all your notes with you as well.
Unfortunately, you'll probably not be interested in a lot of books that you have to read but you may find that you oddly find them enjoyable after properly analysing them. I really hated Chaucer initially but now find it oddly fun to read :/
I did really well in my coursework and really badly in my drama paper and not very well in my poetry paper but absolutely smashed my unseen paper so it all levelled out to an A. You don't have to be amazing at memorising quotes, just be great at analysis and you'll be fine in my opinion.
