What A level should i drop for an Economics degree

Hello, I hope everyone's AS/A2 results went well.
I have a bit of a hard decision to make, so I was hoping you guys on here can help. I want to study economics at a Russell group Uni around the bath, Warwick level. Here are my AS grades:

AS Ocr Chemistry A: 119/140 (an A was 108)
AS AQA Physics :A (don't know my marks yet)
AS Edexcel Economics :got 69/80 in Micro (an A was 59), and haven't received my macro result back
AS ocr mei maths :A C1:B, C2:B S1: A (full ums)
I was very happy with my grades overall, but the problem is that my AS maths result is too low, (as I had a bad day, and the pressure got to me), so came out with only 85 UMS on avg, hence I wont be predicted an a* in a2 (which is a requirement of top
Russell group unis in economics). Is It worth applying for economics?
I am also currently doing my EPQ, but I don't know which subject I should drop and whether I should do AS Further maths or not.
Thank you in advance

I'd say to drop Chemistry as it's probably the least relevant and gets really tough at A2. You don't need to do FM but it could help if you're applying to top universities. Also, you don't actually have to drop anything, but I think dropping Chemistry (or Physics if you wanted) would help you focus on Maths and Economics.

P.S. Bath isn't in the Russell Group.

PS. so what ....?

RG is just a marketing group with a made- up name. It doesn't actually mean anything significant.
