Chances at UK universities

[AeroGuy453]

I'm American working as an aerospace engineer in the UK.

I want to know if I have any serious shot at being accepted to these schools: Oxford and Cambridge. Honestly, I have no idea what is considered a competitive portfolio in the UK.

BS: Civil Engineering GPA: 3.6/4.0

Institution: Georgia Tech

MS: Computational Engineering GPA: 4.0/4.0

Publications

1) 2nd author of conference paper

2) 1st author of journal paper

Race/gender:

White male.

Citizenship:

US

GRE:

Don't remember but it was kinda bad (70-ish percentile for math). I doubt they consider GRE anyway.

LORs

Should be able to get some great ones from top profs once I reconnect with them

I don't like wasting time, so I don't want to apply for these schools if I stand no chance. I know at the undergrad level these schools are irresponsibly competitive (resulting in an ugly rat race), and I wonder if that philosophy applies at the graduate level.
