which is harder, LS3 or LS4?

<p>I'm trying to figure out my schedule...</p>

<p>Winter- </p>

<p>LS3<br>
Chem 14CL<br>
English 4W </p>

<p>and Spring-</p>

<p>LS4
Physics 6C
some Writing II </p>

<p>...or should I switch chem 14CL and physics 6C?
Physics 6C is easier than chem 14CL (very time consuming, I've heard).</p>
