Neuroscience

Hey guys. As of right now I have been using the planning schedule app for BU. I am pre-med(very serious about it), and a neuroscience major. My current course load I plan to take is Chem 101, Bio 107(which is like bio 101), Neuroscience 101, Writing 100(basically english). Now do any of you know how difficult neuroscience is to do as a major by itself or concurrent with pre-med courses. I mean there are easier majors but I want to maintain competitive status for medicla school both major wise and GPA wise. Will this course load as freshman kill my freshman GPA even if I work hard b/c it seems doable as neuroscience 101 is basically a biological oriented version of psych 101, and bio and chem are hard obviously but doable. Students currently enrolled and attending are preferable but any advice will be taken of course. Thank you!
