<p>is it better to choose a major or apply as "undeclared"?
is there any disadvantage to doing either ?</p>
<p>It depends on what school you apply to. For many schools, there is no disadvantage to not declaring a major. However, one advantage to declaring a major would be different scholarships that you might qualify for, just for having that specific major. Some schools require that you choose a school to apply into (like Georgetown).</p>
