<p>Rules are determined by what school you’re in (i.e. your first major), not the class. Thus if your first major you have to say do chemistry/physics/etc rather than non-western perspectives, similarly add/drop dates work the same (based on your major, not what class it is).</p>
<p>Remember that e-school has a very reasonable drop deadline. Thus just load up on more than you plan to keep.</p>
