Why are you applying for Financial Aid?

I’m a student from Dnipro, Ukraine. I am currently 21 years old and studying Cybersecurity in Dnipropetrovsk National University of Railway Transport named after academician V. Lazaryan (DNURT). I am interested in studying Computer Science, Cybersecurity and Artificial Intelligence (especially Machine Learning). Unfortunately, because all courses at my local universities are highly outdated and poorly designed I take all the possibilities to learn from free online resources and I consider Coursera one of the best so far.

I live only for my scholarship (925 UAH or about $37 per month) and a part-time job (30-50$ per month). In this circumstance, it is very much difficult for me to gather such amount of money for the course. Financial Aid will help me take this course without any adverse impact on my monthly essential needs and make a step into wonderful future of possibilities. So I’m badly in need of this financial aid and would be grateful for such a great oppor
