Scheduling help please?

<p>I am SO utterly confused and overwhelmed with the pre enrollment process. And my adviser is not writing me back, which is not helpful. So any words of advice are greatly appreciated.</p>

<p>Firstly, I am an Animal Science major right now, but I want to change my major to Biological Sciences... does anybody know how I can do this?</p>

<p>Secondly, I'm trying to go pre-med... what classes should I take for my first semester?</p>

<p>Thanks.</p>
