When musically trained students get to college, they continue as high achievers, especially music majors. A study of 7500 university students revealed that music majors scored the highest reading scores among all majors, including English, biology, chemistry and math. Also, physician and biologist Lewis Thomas studied the undergraduate majors of medical school applicants. He found that 66 percent of music majors who applied to medical school were admitted, the highest percentage of any group. By comparison, 44 percent of biochemistry majors were admitted.
