The annual family income of a candidate is one of the key factors in determining their total eligibility for financial aid. Alternatively, the candidates can also avail of monetary benefits like student loans, apart from financial grants and scholarship schemes to pay for their studies. But, they should understand that student loans are borrowed at a certain rate of interest, unlike grants and scholarships. While grants and scholarship schemes do not require repayment, student loans should be repaid by the applicants within a given period.
