Bear with me if am off-tracked and abstract.... I am 23yrs old, graduate of a 4 year degree in agriculture ( GPA-77% ). I was forced to do this degree because of my family situation. The world has darken before me & am extremely unhappy with my profession. I am good in physics and maths and wanted to make a career in physics. Does a really good score in GRE general and subject test with agriculture degree ( it's purely biology, no maths or physics course in it), opens the door to prestigious physics graduate schools in U.S? or Should I do a physics degree and try my bet? even i do a physics degree there's no possibility for any research in my country as it's one of the most abandoned course and i can't afford a course abroad. Kindly advice me on this path.... Many thanks..
