Oh right! You're doing GCSE/ in year eleven? I thought you'd completed your AS levels!
Oh, well, in that case, I would highly recommend doing English Lit! Not only is it very interesting and easy to revise for, but it is very highly respected, as is history. RS is definitely less respected, but still more respected than sociology is. English Language is, like English Lit and History, very highly looked upon. Additionally, I might add, a history or english A level opens far more opportunities for more degree courses than sociology or RS. Lit is easy to revise for- you just need to get into the rhythm of writing essays. After you get those cracked its fab, and you get to be creative and opinionated. Be prepared for a lot of content whether you do history or sociology
Honestly, if you haven't even started AS, you can change all three subjects if you like! At my college you could change your subjects after the first week- but many people changed on gcse results day. I did. It's totally normal, don't worry! Better to change now than later on!
Additionally, be prepared. I take sciences and English Lit, and my friends who take sciences say that psychology is difficult (there is a lot to learn, but if you love it it's meant to be easier, as with any A Level). Let me know what you decide, and good luck!
Edit: Also you should know that your college will be completely fine with you changing on results day. Most people at my college did. And, as I've said before, you gotta do what makes you happy. If history, english lit, rs and psychology make you happy then achieving high grades in whichever three you pick is 5000 times easier. They're all respected A Levels. I think history is a slight step up when you get to A Level but only because there is more to learn. If youre good with dates etc then it should be fine. Be warned though, Lit and History have coursework in A2. Kinda time consuming but worth it, I think. Takes pressure off exam
