No. Any major at all is fine. Find what you like and pursue it. You will enjoy your time in school much more if you are doing something you enjoy. Make sure to take Bio I&II, Chem I&II Organic Chem I&II and Physics I&II. Those are your prerequisites. Good luck!
^^i concur
Do something you enjoy! You tend to get better grades if you're more interested in the topic and as long as you get your pre-reqs done, it doesn't really matter.
Go ahead and study whatever you want during your undergrad years. Admissions may even look kindly to someone who has taken a different major.
also, to add to Brain's list, a semester of Biochem and one or two semesters of Calculus should be added tour schedule as well. Maybe a psych for a little flavor.
