Student that wants to continue learning

I am a Biomedical Sciences student at the University of South Africa (Unisa). I am from a township and am the only one at my home who got to University now the greatest battle on my way to finishing this degree is tuition fees. I live with a single parent and from October onwards he will be a pensioner and she is the only one employed at home though my sister works but she is married and have her kids taking of them financially. I want to be the first graduate at home also one of the few in my community. Your help will not be in vain as am a hardworker and persistent person.
