When I applied it was not first come first served as long as you applied before the 1st of July.
And you couldn't reject a halls you were offered and get another one in your list of preferences. If you get offered say, central village, then you either accept that one within the deadline (I think it's 4 days of receiving the offer) or you have to find halls/a house privately
Hey, how do you apply for accommodation? Is it after a certain time or...?
From the accommodation website 'You can apply for accommodation after 1st November once you've selected Leeds as either your firm or your insurance offer through UCAS.'
