Okay, does anyone know if there is a place you can look to see when courses take place?

You can check the course calendar to see what courses there are, but is there any way to find out when/where the courses are?

Like lets say I wanted to sneak into the intro to marketing course and just sit in on it, how would I find out where to go using the internet/mcmaster website?

the master timetable. idk the link, i lost my bookmarks. Under the registrar page though.
