I just meant it’s typical that CSS schools only use the CSS info when calculating what a family can pay (each school has their own formula.) They don’t really use FAFSA, although they do incorporate federal financial aid from FAFSA into the estimated COA that is part of the FA package.
Since you had the CSS Profile in on time, I don’t think any of us will be of help in understanding what happening from the first FA package to the second one…only someone at Cornell can help with that. So, I would have another conversation with a director level or above there. Maybe it has something to do with the business info (which they seemingly had all along, or not.) Good luck.
