Thank you all

Hi every one, I'm new here and I have a question. I graduated from faculty of medicine from Egypt with 70% grade score and I think it's not high. And the problem that during the first 3 years my scores was low ( around 64 %) and these are the basic science years, and during the last 3 years my score was 75 % and these are the clinical years. The question is, are I have a chance to apply for a PhD in Cell and Molecular biology? and what should I do to maximize my chances? I didn't start to prepare for GRE yet and I can give it more time to score high, I love math btw. Thanks in advance
