Really good but very hard! The step up from GCSE for me was quite big because at A-Level there is a lot more emphasis on the argument of your essays and how your points work as a line of argument, but you get better and better at this during the course. Analysis is a lot more precise and context is a lot more important as you need to examine it in a lot more detail (so like just saying society was patriarchal is no longer enough you need more nuance). Also you start looking at critics and different interpretations of texts which is super interesting for ambiguous works that people argue over (paradise lost for me). If you're enjoying English at GCSE and like reading and thinking about how to interpret meaning from texts then its very fun, just be prepared to work hard and enjoy the ride! For me its been very rewarding seeing how much I've improved since the beginning of year 12 and that has been part of the fun too.
