The essay must consists of why I need the financial assistance of the scholarship and what my financial needs are.
This is how I thought to start the essay.
As a single mother and full-time student I am faced with many financial challenges. Rent, childcare, tuition, food, and books/educational supplies are all financial responsibilities that I must I don't know what to put after this HELP!!
Well, since you are applying for a scholarship for studies, I think you also need to convince them that you deserve to be enrolled with their study program. So, in addition to your financial needs, try to present your case as a deserving student. You need to show how interested you are in pursuing this course and how it is going to help you achieve your goals in life. You should not waste too much time on those points since this question is about financial assistance, however, you need to put it in a manner that you deserve the scholarship :)
