Sounds good, thanks!. Reduces my Thursday classes to only one lol.

BTW how do all people know this? i mean im on macinsiders thats why, but for people who aren't on this or aware, is it common for people to attend their labs or tutorials on the first couple days if they haven't had their classes yet, just as a mistake?

Mostly word of mouth around campus. I'm sure it says it somewhere on the McMaster website as well. I'm also sure that there are some people who go to labs and tutorials the first week and will be confused as to why there's noone there.

Generally, you learn from your Welcome Week reps. Then whoever reps the next year tells the new students, and so on and so forth.

You're just a little bit ahead of the pack as you haven't met your reps yet.
