hey, both sociology and English language are essay-based subjects so you can choose either, just make sure your A-level options are subjects that suit you and that you would be good at but trying something new can be exciting as well! 🙂 also make sure it is something that YOU want to do, don't pick it out of force or because you feel like you have to, most universities do have a preference for subjects but usually, they aren't compulsory. Hope that helps!
