hello, I am planning on applying for a molecular biology/genetics PhD in the us. I am a medical graduate from India. My gre scores are 153 quant and 157 verbal. I have 1 year research experience as a research volunteer in the US, but no publications. I was wondering which universities should I apply to to have the best chances of acceptance? What is the ranking range of universities I should be applying to? Are drexel and temple universities too competitive for my profile? Thanks.
