anyone know whether you have to go to your own tutorial, or if it's like 1md3 and you can go to whichever tutorial you want?
the one i want is full but i'm hoping that i can squeeze in since i'll use my own computer anyway

It should mention that in the course outline, or the prof will mention that in class. You can email him now and ask, but it seems weird, you have like 3 weeks until classes start.

You get to pickup your weekly lecture quiz from tutorials, and I believe the whole class' quizzes are brought to each tutorial. So I think it should be fine assuming there are enough seats.
