<p>How does this work? Is it okay to go into a classroom with a lecture currently going on and find a seat in the middle of it all? Or do I have to go to a lecture at the beginning and stay for the WHOLE lecture?</p>
<p>you don’t have to sit through the whole lecture if you grab a seat at the back (there are always students who have to leave early, some of whom don’t have the courtesy to sit in the back and instead make a big show of clomping their way out of the lecture hall … they annoy me)</p>
<p>i actually sat on the stairs because they ran out of chairs.</p>
<p>sit anywhere you want …and if you leave you can either be nice about it and sneak quietly away so usually sitting next to the aisles or the back or you can be a jerk and sit in the middle and climb over people and hit people with you back pack =P</p>
<p>but yeah
=P</p>
<p>Do professors or ta’s ever call on students randomly in the crowd? That woud be TERRIBLE! haha.</p>
<p>not if they don’t know your name :)</p>
<p>i got called on while sitting in the front row of a lecture at UC Davis (multivariable calc, I was still in 1st semester AP calc) and attempted a half-assed answer … it was actually pretty funny.</p>
<p>haha astrina that is amazing. If i get called on…i think im just going to run out</p>
<p>i’d wing it.</p>
