Hey guys, I have heard that taking five years to graduate is frowned upon by grad schools. Is this true, and if so, to what extent? Let me take a minute to explain my situation. I'm a rising junior, and I only decided to become a science major a year ago. I'm a neuroscience major (but you physics folks seem to be pretty knowledgeable about academics in all the sciences). I want to do a PhD in neuroscience after I graduate. Just finishing my major won't be a problem, but I feel like I might lack some upper level science electives. Also, I am becoming increasingly interested in computational neuroscience, and I'd like to take some more math and physics courses, as well as a computer science class or two (I've never taken computer science). Furthermore, I need to take a GRE subject test, and I won't have enough of any one subject. If I do the chemistry one, I'll lack physical chemistry; if I do the math one, I'll lack abstract algebra and some other stuff. How bad would it look if I took an extra semester or two to graduate?
