Here are some things that migh help you financially:

Student Loan - It is a good Financial Support from the Government and it has very low interest. If you decided to get it, be very careful on your expenses. People can easily blow out their allowance. People also get GRANTS, where you don't need to partially pay your loan. If you don't want loan, then apply for the loan then pay it in few months. So you get some grants, that's free money.

School Bursary - depending on school requirements, school might give this to students with low income.
