Chances of getting into a top uni for Economics without FM or Econ at A Level?

Hi, I posted this on the A Level forum but feel it's more appropriate to post here:
I'm an AS student taking Maths, Chemistry, Biology and Philosophy and I decided I want to study Economics at Uni.
I'm planning on dropping Biology and I'm predicting an A*AA for Maths,
Chemistry, and Philosophy respectively. I also have an A* in Persian, but as it's just a native language I assume it doesn't account for much.
I also got 6A*s 4As 2Bs for GCSE
Having not taken Further Maths or Economics, what are the chances of me getting into a uni such as UCL or Warwick to study Econ, given that I achieve those grades and write a good PS? Thanks

you should be fine! due to you having studied mathematics for A-Level it is unlikely that they will turn you down, additionally the A* in Persian will count substantially and you should definitely not exclude this in your personal statement. Im in a similar position however when i was at the Oxford Summer School last year they advised me that they will set another exam judging your math/english skills so you should be okay! sorry that probably made no sense but anyway..

I won a scholarship to study Law and PPE (politics, philosophy and Economics) and i received information on both - what the course entailed and what the application process into oxbridge is like.
I thought the course was very good and it gave me an insight into what life at uni was like and specifically what oxford was like

Damn that's amazing. Will you be starting in 2017? And what did you decide to study? Congrats man!

yeah but i dont think il be getting into oxbridge I studied both while i was on the course and im now leaning more towards PPE rather than law!

Ah there's always a hope I guess, and good choice ahaha. I was trying to choose between Law and Economics at the beginning of the year and went with the latter as well
