1) Sort out your finances
The two priorities are: getting a student account and organising government-funded student finance.
On campus there is a Santander & Barclays so it can be handy if you have a student account with either of these. With my Santander student account, I get a 4-year 16-25 railcard, 3% interest on credit up to £2k, and up to £1,500 interest & fee free overdraft. Incentives from other banks include: £80 amazon gift card & Amazon prime at HSBC or a 4-year National Express Coachcard at RBS/ NatWest.
