here's the letter!!

Financial Aid Appeal Committee,


I am really thankful for the generous scholarship , but unfortunately I still can not afford to attend Alakhawayn University.In fact My parents used to have a (the amount) mortgage that they were struggling to pay, this repayment , rather than its consequences on our financial situation , forebade my parents from making any reserves that could help them guarantee a successful college education to me and to my young brother and sister.Yet, they make only (the amount ) from their jobs.Last june 2006 the mortgage was wholly paid but my parents also need pay for utilities and foods—they are scrambling every DH to pay that. Therefore, I can not see myself asking my parents to take another loan on my behalf. My family simply can not financially support my college education.
Furthermore , i'm very ambitious and one of my main goals to acheive is to own my Ph.D degree in computer science which will allow me to apply for a research center and spend the rest of my life vocariously developing and doing research .with no financial aid it's going to be very difficult to succeed , espacially when my parents should finance my young brother undergraduate studies , which will start next 2008/2009 .Can you imagine how precarious can it be to get in such an experience!?? i don't have any doubt that my brother will apply for alakhawayn university too .Moreover my sister , who is a high school student , study in a private school what means she needs extra charges than me and my brother used to need.
There is no doubt in my mind that I will succeed at Alakhawayn university University. Altough i hadn't gotten a very remarkble mark on my school-leaving examinations leading to university entrance qualification due to some very personal problems , I corrected most of my academic weakness.

University of Lille gives me great facilities. However, I decided to come back to Alakhawayn University because it has wonderful teachers, staffs, and learning environments.I will discover the english world and ithe enormous occasions and opportunities it offers to me to better succeed in this life.

I am convinced that with the help of this committee I will able to finish my college education. I want to express my sincere appreciation for giving me the opportunity to explain my financial circumstances. I am looking forward to hear good new from you.

Sincerely
