Chances of applying to UCL/KCL/LSE economics with A*AA

If I apply with A*AA (maths, fm, econ in that order) + Chem AS (grade yet to know but could be A/B) do I stand a chance at UCL/KCL/LSE, that's the minimum requirement for all 3 of them for anth economics related at those unis. Ik they're really competitive, but if I get a good TMUA score (5+?) does that mean I still stand a chance with a good PS? I'm wondering whther they would be a waste on my applications. I know sm who got rejected with A*AAA from UCL+LSE but w a very low TMUA below 3 for eocnomics so i was wondering if it was her tmua score that meant she got rejected or if she was probably not gonna be considered anyways as she only met their entry requirements minimally.
Also I know KCL doesn't want the TMUA, do i still stand a chance by just meeting entry reqs?
Please reply with harsh reality 👍

Yes you still have a chance for UCL and LSE, just focus on getting a very good score on the TMUA and writing a good PS, as for KCL a very good PS. Is there any chance you can get your predicteds bumped up before January? Also what were your GCSE grades, if they were high it might give you a little bit of a better chance.
