Could I get into LSE and/or KCL?

nothing is 100% certain but i don't think your course is as competitive as econ so you will probably get in. kcl is not hard to get into imo its so overrated. lse is hard but w/ your stats i dont see why not

Currently I am in year 13 studying a-level accounting, economics and mathematics and as-level further mathematics (with my predicted grades being A*A*A*A). To add on, I got an A in LIBF Certificate of Financial Studies. I've sent my UCAS application already and I'm kind off stressed out about my choices.
So I'm just wondering if my grades on the surface allow me to stand a chance at studying Financial Mathematics with Statistics at LSE and/or International Management at KCL.
These two universities would be a dream to get into so any sort of reassurance or 'yeah no you're definitely not getting in' (so I can lower my expectations) would help lift a few weights of my shoulder.

You have excellent A-Levels and will be competing against other brilliant candidates, so LSE is a true lottery. However, KCL will not be difficult to gain an offer from. Don't listen to KCL's reputation being over rated?! 😧 It is one of the best universities in the world and here in London. Obviously Imperial, LSE and UCL are slightly higher in the rankings but KCL is a fine world class university too. 🙂
