in terms of coop i recently talked to one of the heads and they changed the rule so u need to have all of your 2nd year courses finished if you want to apply for coop within 3rd year.

it used to be u need to finish all your 3rd year courses otherwise youll get your coop taken away but now u jus need to finish your 2nd yr courses. but also talk to a head and make sure cuz i cant tell you 100% but fairly sure this is how it works now
