<p>You can change your entire schedule (except for the ENGR 100 class) without telling your advisor. However, it would be nice to tell your advisor about your AP credit in Physics, just to keep them informed. So, you could replace Physics for anything else, as long as ENGR 100 stays the same. </p>
<p>Finishing off the humanities/social science requirement is a good idea, you always can take a 300 level class and finish off two requirements: one 300 class in HU/SS and a series within a subject field (i.e. English, PolSci, etc.).</p>
<p>Hope this helps</p>
