I'm also just an incoming M1 so take this with a grain of salt lol
- Groupme is invite only, you should either get added by the admin or he'll send you an email with the link. Might take a bit so don't go crazy if its not asap
- yeah lecture attendance is mostly non-mandatory, i think the small group stuff and labs are mandatory but big lectures are also streamed if i'm not mistaken
- there's an apartment complex across the street that lots of M1s live at, but otherwise students live all over the city. Clifton isn't the best area so that's something to take into account, and UC main campus is also right there, so lots of undergrads live in that area too. some even choose to live in NKY, so it's really your preference. here's UC's COL estimates for each year:

- pretty sure it's a mix, but i'm like 95% sure the have at least some NMBE style. don't quote me on it though lol
