<p>As I've been noticing, a lot of upper-tier colleges require 3 science classes and all of those need be 'lab science' courses.</p>
<p>I have taken biology, chemistry, and taking AP Environmental Science this year.
However, I am not scheduled for physics. </p>
<p>Is it necessary for me to take physics this year or will APES, biology, and chemistry suffice for the required 3 lab courses?</p>
