An undergraduate degree in philosophy provides excellent preparation for almost any line of work, especially when combined with career-specific courses and extracurricular training. This is because philosophy trains people to think. National test score data and graduate school admissions show that studying philosophy can be of significant benefit for prelaw and premed students as well as for students interested in public policy, business, and a wide range of additional professions. 

The key to career preparation is to study what you love, do well, and make sure that you put the necessary career-specific training and experiences into place. For instance, if you are interested in medical school, you can major in Philosophy and either double major in a science or make sure that you take sufficient courses to meet your premed requirements.
