Physics 4BL how to switch with someone

<p>i'm first on waitlist for 4BL Lab 5 (Thurs 8am-10:50am), but my second pass class is full so I have to change my schedule. Is there anyone out there who wants to switch Lab 5 for Lab 2, 4, 7, or 8? how do we do this without each of us losing our spot?</p>

<p>you can’t switch without losing your spot</p>

<p>both of you would go to the back of the waitlist</p>
