I have done my Btech in Biotechnology in Chennai with a CGPA of 6.4.
Followed by MSc in University of Kent at England with a percentage of 52.
I wish to pursue PhD in an US University, but I am confused if I will get a scholarship or not with low percentages.
Well, typically PhD admissions are dependent on your academic publications in the field of your interest. Also, recommendations play a vital role. You can offset your percentages with high GRE score and maybe take subject GRE to prove the same. Admission for PhD is a holistic decision and not just based soley on percentage. Do proper research on schools and apply with good scores, you will get scholarship.
