Help me finish my renewable energy degree...

Hi, I'm Amadi. I am in the final year of my Masters degree in the University of New South Wales in Sydney and I am particularly interested in bringing renewable energy to developing communities back home in Nigeria. I have been working hard to finish my degree while working 32-35 hours a week in aged care. Unfortunately, though this job used to be enough to meet my spending and my tuition, I am currently still owing the school $8000 and have to pay it by the 17th of September or I won't be able to continue my studies, I can't work any more extra hours at work and the rent in Sydney is has been so high that I could not save up enough in time.
