you may try to apply, since the application fee is not expensive.
but don't expect Oxbridge.
Oxbridge is way more difficult than other G5, as those 3 universities in London offer lots of master to get $$, i.e. way lower standard. (LSE, IC, UCL flagship program can be still as competitive as Oxbridge one, but they offer a lot others, which Oxbridge raraly have that)
No one fuxking care your GRE, it is all about your GPA, GPA, and GPA.
If there is another thing that matters, it is your undergraduate institute, which measure the quality of your GPA.
