Heyy I'm a Muslim and inshallah i will be going to Plymouth uni this year! I don't know too much but I already live in Plymouth, if I can be of any help - I think beckley point (I only know people who live here) or astor house are good options for accommodation, some others that I've seen people talk about are Francis drake or Mary Newman which are both on campus but all of these are very close to the uni so I wouldn't worry about being able to get to class.
As for anxieties about moving, ik it's scary but trust that you'll have lots of people there to welcome you, myself included! There are also lots of societies and I'm pretty sure there's a new group chat at the start of the year for new students? Idk if not then we can just make one lol but point is that there are gonna be lots of events and stuff to help get to know everyone (including ISOC - the Islamic society!) so inshallah I'll see you guys there! ♡
