Student Loan

Hi,

my sister wants to go for a student loan as she is an EU student coming for 1-year degree ( masters degree ). I have some questions in whether it's beneficial to take a student loan.

From what I understand, interest and repayment starts after her first salary above a threshold. But the minimum payment is so low, that if she continues with the minimum the overall amount will be almost double by the date is fully repaid.

I am not sure about the early repayment so I am asking whether the below scenario is a valid one :

1) My sister takes a student loan.
2) I help her repay it before even the interest starts ( meaning before she starts working ).

Or in other words, I can either stuggle and give her the whole fee now - or pay that gradually in the next 12 or 18 months, where there is no interest charged on her loan.

Can I do that ? Or should the loan be repaid by her salary? I see there is no fee for that, but... is it true?

Many thanks
