Changing classes during first two weeks

<p>I was just wondering how many people actually change classes during the first two weeks? I was waiting for a class to open up because my growl wasn't working when a slot opened and I couldn't get the slot...</p>

<p>I also heard that you shouldn't change around classes for the first two weeks because so many people are waitlisted and such... Any info on this?</p>

<p>Thank you in advance as always =]</p>
