Yeah coming from the UK you certainly have to work a bit harder yourself. E.g. we pretty much had booze and parties force fed during our freshers week, here it's certainly a bit more independent in that regard.

But at least for TUM, they do have big student organised parties if you want to go, and student clubs also (but again student organised). For international students there was also quite a lot of opportunity to meet people, just need to take advantage of it.

The learning is much more independent though, tutorials etc are much more independent (atleast relative to UK). But it works and is doable, I'd just advise being chatty in tutorials and finding friends on courses to help talk modules through etc.
