Saving money before uni

Hi everyone, hands up who else is worrying about uni already when it's months away lol?

I will be working as much as possible up until then, but what is a REALISTIC amount to take to uni with me? I know as much as possible, but roughly how much would get me through a term at uni? Or how much should I save up before starting uni?

Thanks, congrats anyone who has been accepted, and good luck to anyone still waiting!
