<p>You don’t major in pre-med. You major in something else while taking the pre-med courses (chemistry, organic chemistry, biology, physics, English writing, sometimes calculus and/or statistics).</p>
<p>A large percentage of pre-meds major in biology, since biology major requirements include the pre-med courses anyway. However, biology majors have relatively poor job and career prospects at the bachelor’s degree level, possibly because of the large number of pre-meds who did not get into medical school competing for the low paid lab technician jobs.</p>
<p>But pre-med courses can be done alongside non-biology majors like math, statistics, economics, etc. (although it may be harder to do so if the major has a lot of non-overlapping requirements, like engineering (other than bioengineering or chemical engineering) or business). Some such majors can be useful supporting majors to a medical career (e.g. business can help a physician in private or small group practice) or offer backup job and career options if one does not get into medical school.</p>
