You could potentially try and compromise. Tell them you would like to move out for 1st year so you can settle in and really focus on your studies, whilst also making new friends. Try and find a prive halls studio so that if they are worried you will be distracted by flatmates/wild parties, you can show them you will have your own privacy. Then for 2nd and 3 year tell them you will move back home. The idea of this is to either one, after 1st year they will ease up and let you continue living away as they can see how hapoy you are and how good your studies are going or 2, if they don’t then just stay living at halls anyway. Basically tell them what they want to hear to get them on your side, but the overall goal is to try and get them in your side but do what you want after that.
The advice of just screw them is no good. Because what if you get accomodation which doesnt cover the holidays. Where do most students go? Back home. How will you do this if you left on bad terms? By all means you can go rouge, but just know theres consequences. You never know, some people move out and end up hating it, so it is nice, at least for 1st year to have your family home as a backup.
I’m sure your parents main concern is you doing well in your studies. So you’ll have to show them how living indepently and closer to campus/24 hour libraries, will benefit you.
I ended up not moving out like i wanted to and i regretted it. Lost all interest in my course and uni and my grades showed aswell. Now I’ve reapplied for the uni i wanted and I’m moving as originally wanted and i know i’ll be more motivated this time. You can use that as a con for staying home when talking to your parents e.g statistically 78% of students who live at home end up getting lower grades than students who are more involved in univeristy life in halls. Obvs I’ve just made that up but you get the idea. Blag it!
