The grants went up for student 1 over the years. Grants for student 2 were @ the same. I wrote letters for both students that did lower the out of pocket costs for both. “Drastically increase”? IMO, no.
BTW - based on your questions, you should have a serious conversation with a Fin Aid Rep, and discuss your particular circumstances. What occurred with my kids may not in fact be applicable to you, so if this is important to you, make the call(s) and have numbers in front of you when you do. Good Luck!
