<p>The problem with majoring in biology or chemistry is that there is an oversupply of graduates relative to the jobs in that area. Biology is a very popular major, because a lot of students go to university with the dream of going to medical school. Even though no specific major is required, most of them major in biology. But most of them do not get into any medical school.</p>
<p>Physics jobs are not that numerous, but the supply of physics graduates is much smaller. Also, the “surplus” physics graduates get recruited into well paying jobs in finance, computer software, and some areas of engineering.</p>
