Any way that you want. You can use the money to pay your tuition fees, put it towards your living expenses or you can use it to fund both.
If you are lucky enough to have the opportunity to study abroad during your course, you can also use your loan to cover your time outside the UK.
If you take out a tuition fee loan, we will send the tuition funds directly to your University. Cost of living funds will be transferred to yourself. Typically they are disbursed over a number of months, you'll receive a detailed disbursement plan with your loan quote.
