<p>if you ever had a class that late, can you tell me whether it was worth it or not?</p>
<p>is it a discussion? if so, for most discussions, these are optional and you can attend as you please, or attend a different (earlier) section. i remember lol-ing when i saw the 9pm math discussions two years ago. but i didn't sign up for the 9pm one...nor did i ever attend my math section.</p>
<p>yes! first quarter frosh year my chem section was that on thursdays!</p>
<p>it was worth it bc i was in the class but it sucked becuase that teacher had quizzes in those discussions instead of in class, so it was a real bummer, id be way tired out and i had to make sure i remembered i still had class left at 9pm!</p>
<p>If it's a discussion in which the TA teaches multiple sections, you can usually request to just sit in on one of their earlier sections to take quizzes, etc. As long as you're consistent and there's space in the classroom, it shouldn't be a problem.</p>
