Being in a unique situation I'm hoping some one can give me some any advice as I begin my application process.
My background consists of 4 years in the Navy as an electrician, a BS in Environmental Business with a minor in philosophy. Upon completion of my degree I realized I wanted to pursue a PhD in neuroscience, so I began taking chemistry, math, biology, physics, and psychology classes, but not towards any specific degree. I also found a position at a research lab and have been diligently volunteering for approximately 8 months. Where many NS programs do not restrict the entrance to certain bachelor degrees I'm thinking that my lack of a specific discipline focus will hinder my competitiveness.
As for LOR my PI and an old Lt. have said they would write a letter. I'm on the fence about asking a professor in my old program since his field (environmental science) isn't really relevant to NS. Should I ask a random biology/psychology professor whom I received high marks from that I haven't established a rapport with or use my old professor who knows me well?
Also do I stand much of a chance (aiming at state schools) with a current GPA of 3.75 and GRE of V 162 and Q 151.
Thanks for your time
