Are tutorials/labs times for bisc 102/phys 101 flexible?

Ji8

Hey guys,
I'm planning to take bisc 102 and phys 101 for summer. I'm just wondering are the physics tutorials mandatory that you go to the one you sign up for or can you go to any one like with the chem 121 tutorials? I'm taking it with xiaoke/michael chen.
As well as with the bisc 102 lab and tutorial, are they flexible or are we also required to go to the one we sign up for? Lecture is with Ron Ydenberg and lab is with Erin Barley.
Thanks for any help

When I took phys 102 with Micheal Chen we were allowed to attend any tutorial, they were however mandatory and will have participation marks.

for bisc 102 lab, there is no attendance, for tutorial there was attendance for us (depends on the prof) .

There is also attendance for michael chen's tutorials.
