Admissions Appeal Letter?

I think it is a well written letter. However, if I was the person reading this, I wouldn't let you in the program. You say if you were let into the program you would work 110%? The do that first and then I would consider letting you in. Don't forget that there are probably plenty of students who have much higher gpas who already work at 110% trying to get into the same program and so this part wouldn't make me sympathize with you. It great that you mentioned that you're using academic support. I would change the nursing program part so that it read more like you finally got out of that confusion and decided what you want to do and that you know that it will be difficult to achieve and that you are willing to work hard for it.
