Many people that if they wish to be admitted into medical school, they have to major in the sciences. As a result, many feel that biology, chemistry, and physics are the only options. This is just not true. You can go into any major and not have to worry about being at any disadvantage among other science-majoring applicants.
There are some that believe that being a non-science major will actually make you stand out. This is only partially true. Being a non-science major will not increase your chances at getting into medical school. Having said that, if a History and a Biology major are equally matched in every aspect, the edge might go to the History major. The student body thrives on diversity - if that's the case, why take another Biology major when they already make up more than half the class in medical school?
So are there any benefits of being a science major? Well the first advantage is being better prepared for your MCATs. The second is you will have more of a base for medical school than other non-science applicants. If you're becoming a biology major for these two reasons - stop. There is no point in entering a major for the next 3 to 4 years of your life if it will make you miserable. You can fully prepare for the MCAT without being a science major and perform just as well as your peers who are science majors.
Do what you're interested in - chances are you'll be asked "Why did you major in X." The honest answers are usually the best - especially if you have a deep interest in your major.
