This isn’t the question you asked, but if “1-2 in state schools and 2-3 Ivy Leagues” is the total extent of your child’s college applications list, I’d encourage you to search for some more schools that will offer your son merit money. Any student who is in range for schools like the Ivy Leagues is also going to be able to find schools that will offer non-need-based money.
Of course, if he’d be perfectly happy with the in state options, then no need to do this. But it would be another way to save money.
