For psych 1xx3, the tutorials are basically a place where you get to apply what you've learned in the lectures, and at the beginning there's usually a mini-review session. You get marks based on participation, and I felt they helped with the material.
Bio 1m03 tutorials covered a variety of different material, but there is also a PBL project involved. I would say that the actual time of the tutorials isn't very important, but it's not such a good idea to miss any of them since there are marks for attendance in psych, and assignments to submit for bio.
