Why would they have to do this? No university will turn away a cash paying applicant.
Oh, yes they will. Most colleges are now need-blind. My daughter and son-in-law have their kids’ tuition all saved and ready to go. I asked my son-in-law if the fact they won’t need any aid will help them gain admission and he said no. He’s pretty well acquainted with college admissions as he works for a private school.
