Slightly disagree. For the less scientifically gifted but still competitive applicant, being a humanities major is a boost for many reasons. First med schools do not want an entire grade of bio and chem majors and most top medical schools could. So diversity is a plus and Classics is pretty diverse. Frankly classics sounds hard. However honestly Poly Sci does not and I think that gives your GPA a boost over your chem major. Most medical schools do not care what you get As in as long as they can say 90% of our class has a GPA of 3.7 or whatever. You must have at least a B or better in your required science classes.
