The weekly tests are a joke. If you make an error, they show you the correct answer and you get to try again. If you fail to get 100% with that, then they only take your best 5 anyway so you have multiple chances to fuck up.
The group assignment is like every other one; match with idiots and you'll hate it, but it's straightforward if you get competent people. It's not particularly hard and the content is actually somewhat interesting - you choose a macroeconomic topic/phenomenon and make a presentation on it.
The exam is a piss easy MC one. I did not even study for it and after calculating backwards, realized I got 90+% on it.
You'll probably see a lot of non-Business students in this subject, as many Engineering students take it as part of a double major/degree with Business.
