However, an admission committee would expect an applicant to do well with either degree. The B.A. degree requires greater breadth of studies and this, too, may be attractive to all admission committees. Committees look at the quality of the transcript rather than the name of the degree. If it interests you, yes. Admission committees look at the level of difficulty of an applicant's course work.
Classes are often smaller, and classmates are similarly motivated achievers.
Medical schools look for quality in an undergraduate curriculum. A double major or an added minor are only two of many ways to show academic interests and abilities. They are not necessarily preferred. Rather than create a long list of possibilities, let me suggest that you undertake an adventurous approach to the curriculum, designing what will challenge and interest you. Most medical schools require one year each of general chemistry, organic chemistry, biology, and physics.
