waitlist question?

<p>I am on the waitlist for IAS 45 with lough, and I am #13. However, on the online schedule it says there are still 11 spots left for "instructor approval". I'm not really sure what that means, but what is my chance of actually getting into this class?</p>

<p>bump…?</p>

<p>I’ve heard that chances of getting in from the waitlist are pretty good for 10% of the class size. Of course it varies from class to class.</p>

<p>And i don’t understand either what those remaining spots mean. I think they’ll fill those up with waitlist students if no one enrolls.</p>
