Is it fair to expect high grades when paying for college?

At the college level the student is provided equal ACCESS to education, but the student is responsible, not the school. That said, many, many years ago a school not only allowed a student with a sleep disorder to manage to avoid morning classes, but they did actually go out of their way to offer for someone to call the student to help wake them up!! That was not required!! But they were kind enough to offer it to the student. No recollection if it was used or was successful! Also can’t recall if it was before or after the ADA laws (written in 1990) were amended (2008), or even if that mattered.
