How hard is it to get off the waitlist?

<p>Right now I'm #9 on the waitlist for Spanish 4. Because I would only have 9 units without it, I had to sign up for Asian Studies 10 which I'd really rather not have, because I really enjoy Spanish and feel like I would do better in it. </p>

<p>So, what are my chances of getting into Spanish? Even if I get in, what if it's like 2 weeks into the semester, wouldn't it be bad to have missed so much of the class? Or is it possible to try to sit in on the class even though I'm on the waitlist?</p>
