We are in Alabama and my oldest is a freshman at a state school. They don’t offer any need based aid that I am aware of, unless it is an endowed scholarship. He has the full pell grant, academic scholarship, leadership scholarship, leadership housing scholarship, small honors college scholarship, and local outside scholarship. It is enough to cover everything but everything except the academic scholarship had to be applied for and most things were only for first time freshman(renewable though). Our state just doesn’t provide much in the way of financial aid. Everything is either federal or institutional based on certain requirements/accomplishments. Perhaps Louisiana is the same way.
Maybe talk to the financial aid office and see if there are any endowed scholarships that you can apply for to help you get finished. If you happen to be female, maybe there are funds out there to help women going into chemical engineering.
