I have a 3.26 cumulative gpa, with a 3.1 major gpa. I have one and a half years of research experience. One year for Neuroscience research and 1/2 a year in Chemistry research. I haven't taken the GRE General Exam yet, I'm studying for it now. Oh and I got a D in Biochemistry which was my only D ever. I was wondering if this will prevent me from getting into a Neuroscience PhD program? I'm planning to take the Biochemistry GRE Subject Exam and studying for the exam for 4-5 months.
