What's the screener?

<p>I was recently accepted to Loyola. I am pre-med and planning on majoring in chemistry and was wondering what its main science “screener” class was. If anyone knows it would greatly help me make my decisions. Thanks.</p>

<p>i.e. biology, chemistry, physics…??</p>

<p>First 3 required intro classes</p>

<p>Is there any way to skip the intros?</p>
