4as levels needed to do law at Oxbridge ?

Yes. If not it'll hinder your application a fair bit because most universities (not just oxbridge) would expect 4as's then 3A2s.

However, there might be people that got in with 3as grades, i'm not sure. Can't you ask for extra help outside of school? Or maybe even change subject if you're willing to catch up with the work?

Hi, I'm currently doing 4 as levels - history, government and politics , geography and psychology. Im really struggling with politics and im just not doing well in it , I didn't want to choose it but felt compelled too because obviously it'd be a good subject for law.
I'm considering dropping it as I don't want my other subjects to suffer , the time I spent revisig politics could've been spent on my other subjects. I really want to go Oxbridge or any good university but I heard oxbridge like 4 as and then 3 a levels. It's really stressing me out as I really just don't get politics but I feel like I have to keep it :/ please help me
Oh and I got 4 a* 5 a and 2 b at gcse's if that's relevant.

You really need to keep all 4 AS levels I'm afraid. You're going to be applying against almost everyone else who has 4 AS's and Oxford probably won't even give you the chance to justify why you only did 3. You'll stick out like a sore thumb to be honest.

I was in your position last year and came so so close to dropping geography and doing 3 AS levels. I'm glad I didn't as I wouldn't have got a Cambridge offer for Law.

Politics is all about reading around the subject, watching the news and keeping up to date, particularly at AS. You're going to need to push on through the frustration, go through your textbook and learn the theory (pressure groups, parties, elections etc) and do your best.

Other universities will consider you with 3 AS's, but I highly doubt Oxford would. The competition is always fierce, particularly for Law.

EDIT: you are doing the same AS levels as I did btw

Ahh right :/ yeah I guess will just have too and hope for the best. Thank you very much how did you cope haha

I got my head down and got on with it! That's the kind of attitude you need to show if you're thinking of Oxbridge
