The short version is that Biomedical engineering and Physics are at the top of the list on the MCAT. Scores are given in three areas. Physics is best in Physics sciences (duh!) and tied in verbal reasoning. Only in biological sciences do the engineers pull ahead. For those of you who still think it is OK to major in Biology to go to med school, note that Biology is next to last in the list. The only major worse if Premed!
On the LSAT, Physics is the clear leader. Once again, Pre-law and criminal justice are at the bottom of the list. Even Political Science, where most applicants major is well down on the list.
The clear moral of this story is that if you want to be a lawyer of a doctor, Physics is the best place to start. Of course, if you want to be researcher, teacher, engineer, business person, or anything else, choose Physics.
