If I have a tutorial for the first class, do i go to it, even if we havent had a lecture?

Tutorials generally don't start the first week or two (or basically until the prof tells you they're up).

Psych 1X03 is probably an exception (though it's been 3 years and the course has changed since then so not sure).

You should check on avenue as the prof usually posts a notice about when tutorials/labs start.

There's nothing to cover in a tutorial if you haven't had at least a few lectures. There's usually no tutorials until the 2nd or even 3rd week of school. The prof will tell you when they will start during the first class.
