<p>Don’t make up any pre-decisions about wanting to be what until you get through at least your first year in college. The number of people who start off as pre-med and end up moving on is always a large percentage every year.</p>
<p>I will tell you that you are right in that it is probably the most difficult to be a biology major, start off as pre-med, and then end up not knowing what to do with your life after quitting pre-med. While it will be the most difficult to manage if you also plan to be pre-med, engineering fields of any kind are the most employable and probably “useful” in that sense if you do not plan on going to graduate school. In terms of non-engineering majors, math/econ and/or physics do end up having the highest applicability to any subject, so those are the “safest” to do (i.e. if you do not get into medical school, you can still go to grad school for pure science or engineering, move into a real job in industry, go into finance, etc.) however they also will probably result in a lower pre-med GPA.</p>
<p>So in the end, the moral is that if you want to major in something science related, yet have good back-up plans while still being able to have the option to do pre-med, nothing is going to be very simple and you should try to make up your mind sometime after the first year of college.</p>
