Hi there

I'm currently in Year 12 and thinking about my next steps now. I had a think about which subject to study at university and I'm now considering History. The glaring issue is that I'm not doing it at A-Level. My current A-Levels are English Literature, Spanish, Media Studies and Maths. I don't have conclusive predicted grades as of yet but I'm aiming for A*-B (at the least) and I'm averaging As in all of my subjects except from Maths (closer to a B). I'm also considering higher ranking (preferably Russel Group) universities for my higher options out of 5 for UCAS - would it be possible for me to get into Oxford History or History and English with those subjects and those grades? I do 4 so it is possible for me to ignore Maths in a way, seeing as it doesn't really fit at all (I chose it when I wasn't sure what I was into but I'm not going to drop it now). I feel REALLY quite passionate about History, more so than English Lit - I got a 9 in History at GCSE and really loved it. I TRULY regret not choosing it at A-Level - but I can't do anything now. I'm feeling very dejected about it all but I'm hoping it's not totally impossible, and I'm willing to work hard for it. Is this AT ALL possible considering the circumstances?
Also, I'd like some tips for work experience and the kind of things that I can put on my personal statement because I don't really have much right now aside from roles such as House Captain (I know, I'm not really helping myself here. It's been hard to get opportunities and I'm not a very outgoing person.) Would some kind of online course or in-depth research on a documentary/topic help me? How about a blog (my friend suggested this)?
I have one more question, and it's regarding the written piece(s) of work to apply at Oxford (and possibly other places - I haven't checked). How would I do this without History (again!) - would I use my English Lit essays instead??
That is all, thank you very much for reading. Please feel free to apply to whichever section you please, but preferably the first.
