With so many things to do, be careful to budget to avoid frittering away your first month's spending money at Freshers' Week. The student bar, student club nights and gigs will be cheap, but not much will be free. Many of the societies plying for your membership have costs attached too.
You might want to set aside a set amount for Freshers' Week to cover all of these extras. Just remember to include that in your budget and cut back on other weeks, so that you don't spend more than you can afford over the first semester.
A totally fee-free student account with an optional overdraft like FlexStudent, could be a good safety net in case you do spend more than you planned. FlexStudent has a range of features to help you stay on top of your money, not just in your first term, but throughout your course and after you graduate. (Account opening criteria apply).
