Hey, I'm a Warwick first year, I've recently started a job as a student ambassador which is an on campus job helping with open days and widening participation.
You can also get jobs with the SU at the bars, pub or the club.
Cannon Park is also a 5-10 minute walk away with Tesco, Wilko, Boots and others if you'd prefer a retail job.
Accommodation, personally I'm in Arthur Vick, it's very nice having an en suite and kitchens and Warwick Accomodation look after you if things break (which hopefully they won't!) I have friends in a variety of accommodations on campus and even Whitefields I would describe as liveable.
Most accommodation is mixed gender, but single gender areas are available
Social life, there are loads of societies on campus so there is always something to do, not drinking is no problem and there will still be lots to do, most societies will also let you circle (drinking games) with non alcoholic drinks so never feel like you have to drink. You don't have to club if you don't want to.
Any other questions feel free to ask
