Any chance for a PhD in Epidemiology with my background?

[janh]

I had a undergraduate degree in pharmacy in an university in Mainland China (GPA is just fair), and an MPH in the University of Hong Kong.

 

And 2 year research experience in health policy, and then 1 year in epidemiology.

 

1 paper under review, not published yet. 

 

And which GRE score should I submit, since I have taken twice, results as below:

 

V152, Q170, AW4.0

V158, Q164, AW4.5

 

Is it a bad idea to submit both? 

 

Thank you!
