<p>When you apply to a school they usually ask you what you plan to major in, well does this mean you have to chose that major after enrolling? For example, could I have applied to Hopkins for mechanical engineering and then switch to Biomedical engineering, one of the best departments at hopkins.</p>
<p>No, you won't be bound to that major. A kind of sneaky thing to do is to put down a major that isn't very popular at that school. Like, at an LAC put down a science-y major and at a tech-y school put down a liberal arts-y major, Its sneaky but it can work.</p>
