Anyone from Bocconi in this forum?

I'm a current undergrad student at a US university, and I'm thinking of doing an exchange at Bocconi in Spring 2022 (hopefully things will be normal by then?) And I was wondering if current students at Bocconi, ideally native Italian undergrads to give me more insight into life at Bocconi.

For context, I speak pretty good Italian (C1) and plan to take some (if not all) of the finance-related classes in Italian. One of the main reasons I want to go there is to really improve my Italian and to get the brand name. I've also secured an IBD internship in London, and ideally I'll get a return offer and go back next year. I know basically all Italians working in finance in London went to Bocconi so thought it'd help with networking as well. 

I guess my questions are:

1) How hard is it to take classes in Italian as a non-native? Are the exams really done orally?

2) Do exchange students hang out with native Italians? I heard there is a ton of exchange students there so they hang out among themselves and don't really mix with Italians? The last thing I want to do is hang out with American/English students and become one of those who just speak English all the time.

3) How's the nightlife/party scene?

4) Is this the right forum? lol
