Question about lecture sections!

<p>So I got back from my A&O session a few weeks ago, and I have a question about lecture sections. For example, there's a Psych 101 class, section C in Kane 120 from 230-320, and it says "WITHERED TO 101F & 101J", which are at the same time, same hall, and same instructor.</p>

<p>My question is, why are there different sections for the same lecture? Is there a difference between which section one chooses to enroll in? I'm assuming the 3 sections comprise one lecture, but do the sections get divided up during the course of the class?</p>

<p>Thanks in advance, I can't seem to figure this one out now that I don't have a counselor to ask :P</p>
