reccomendations

Hi! So, I’m going to be rushing for Fall 2018, and I had a question: do sororities like reccomendation letters? I have heard that some don’t even look at them when they receive them, but I have also heard that they make you stand out during the recruitment process. I know it varies from school to school, but does anyone know how the sororities at KSU feel about them? And more specifically Phi Mu?
