Unfair practices in Georgia Nursing School!

I attend a nursing school in Georgia. Right now I will not list any names. Over the past few months since I was booted out of the program a lot of info has come to me about the nursing program that I was in. Things that I have found out have to do with unfair practices that are going on in this particular program. Some of these unfair practices fall along the lines of race and students remaining in the program when it is widely known that they have broken policy. I want to right a letter to the president of this university to have some of these practices looked into. I just need a little advice about what to do and how to go about this situation. I am tired of seeing so many of my peers in the program being treated unfairly!
