From the awards I’ve seen with PELL, it has always been integrated into the school grants. It has been many years since I have seen anyone with financial aid have their expected contribution eliminated by merit. I suspect that except at the very few most generous schools, PELL and merit reduce institutional grants into expected contribution, and all of this is done in house without the workings shown.
I have seen loans and workstudy replaced by scholarships.
In this case, I don’t know if NU has eliminated self help from their financial aid packages. If they have not, I suspect that some of the institutional merit money went towards loans/workstudy and maybe even towards need grants. No way to tell
