Chances on masters Econ at LSE

I am currently a Junior at UPenn
My GPA is 3.75 and I am an Econ major (BA)
I have extensive work experience, internships on Wall Street and in the Public Sector, I am also an Econ TA.
I have yet to take the GRE’s.

One issue I have is I am a transfer student from a lower ranked school, my GPA at the school was a 3.85.
Also I have no research experience.

Thoughts and advice?
