Reapplying to University

Hi everyone,

I'm currently studying maths at Bath University, and have just finished my first semester. However, I have found that I really don't like the course, as the maths on the course is really abstract and not very applied at all (I know I probably should have realised this before choosing maths at university!). I am seriously considering dropping out and reapplying to study economics next year, as it still contains maths, but is much more applied to the real world. My A-level results were: A*-Maths, A-Further Maths, A*-Biology, A-French. My question is, will the lack of economics A-level put me at a disadvantage if I wanted to apply to top universities such as UCL and LSE for next year?

Thanks for your help!
