personal statement for geog but want to do ppe pls

That's so interesting - sounds as if you're really enjoying your course though - good for you!
So in the end, in your case, was there value in adding some criminology/forensics choices onto your application?

Employable in what industry?

im in between finance or law for law i would do a law conversion

The course you study is pretty irrelevant in both fields. Investment banking firms / big finance stuff in London have some large recruitment processes. Some of them have shortlists of target universities they recruit from (which makes this industry the rare rare exception compared to the rest of the UK) but the subject you study often isn't a factor in this to the best of my knowledge.
Similarly for law, where you'd be looking at professional law courses for after graduation, the subject you've done before isn't necessarily a game changer. Whilst lots of successful applicants to these courses chose to do a law degree, many don't and it's not a requirement. Lots of big law firms now recruit uni-blind as well, so the institution you attend matters less too. Now, one thing to factor in is whether some uni courses might help prepare you for doing law better than others. So you may wish to consider how you can be kind to future you and give them some of the skills that will better align with your ambitions.
The last thing I would say is, this is at least 3 years of your life where you need to study independently, often without a lot of guidance from teaching staff. If you aren't motivated by that subject, you're going to have a miserable time. I would choose to degree that I really feel I could enjoy studying solo for 3 years.

i have heard that the finance and also law industry hold large significance towards uni which is why im applying for some of the target unis however im nervous about my chances the unis im thinking of are ucl, kcl,lse,manchaster my gcses werent amazing im predicted A*A*A im eligible for contextual offer as well and went to a low achieving secondary do you think i have a chance im applying for geography at lse,kcl,ucl and PPE at manchester and KCL i saw for contextual offers it drops to ABB for LSE

I have advised you already that for law this is no longer the case.
For finance sadly it is still true.
You can read each uni's attitude towards GCSEs on their website but in the vast majority of cases of you've passed English and Maths then the rest doesn't make a tangible difference to your application.
From the rest of your stats it looks like you have a very competitive application
