Chances of getting off the waitlist for these classes?

<p>Hi I am currently waitlisted for these three classes: Bus-C104, Bus-K201, and Eng-W131
I actually watilisted for multiple sections and the positions are as follows:
C104: 5 4
K201: 8 3 3 1
W131: 2 1 1 2 2</p>

<p>I thinking that getting C104 would be almost improbable so I am not in high hopes for it. But all I need is K201 and I will be able to get into Kelley within 1 semester and I am betting my chances on the 1. So what do you think my chances are?</p>

<p>Also should I e-mail Kelley or the professor for K201 (although it says "staff" for all of the instructors) and explain that I am an international student so I was forced to register for classes late (I have seen successful example, just maybe not at IU; but I was also advised against e-mailed by my advisor during the meeting)?</p>

<p>Thanks in advance?</p>
