Hmm... I don't mean to argue with anyone, but I'm sitting here looking at the yellow booklet I purchased from the BEES office for the Bios1201 course.
The first page is a time table, which states that the first hour of our three hour labs are "Tutorials/preparation". It also states that there is no practical component in the first week, but there is the first hour tutorial. ie, if you're lab is Tuesday 2-5, there is a tutorial at 2-3 (first week is "introduction: lab rules and safety") which goes for an hour. In the first week we will finish at three.
I'm not trying to be a smart arse or anything, I'm just telling you what I see here in black and white and hoping to clarify some stuff.
EDIT: Page 6/7 of the book: There are two types of tutorials in this course. Face-to-face tutorials. These are run for the first hour of the alloted practical class time
