Currently taking stats 2B03. Wondering how the labs are like i.e. hard? time consuming?
also which TAs are nice and more helpful in the stats labs (names please) because I plan to do all my assignments in the lab.

When I took it, the labs weren't too bad. Just step-by-step assignments.
The TAs aren't necessarily the same every year. Most people don't even go to the labs and just do the assignments at home, so you really shouldn't need that much help anyways.

Labs are easy. Facebook groups for Stats were the most useful resource for me. Try to see if someone made one for this year.
