Hi guys, I'm an international student and plan to apply for cellular biology Phd programs in United States. My GRE score is very low, just 146V 167Q and 86 Toefl. But I have 3.9 GPA, 2-year scientific experience, summer research experience in United States and 3 good recommendation letter. Is it true someone like me will be rejected just according to my GRE score? Admitted by top school, such as Stanford and UPenn is impossible? I will retake GRE and Toefl this month, do you have some suggestions? Look forward to your reply.
