If the school’s actual FA offer is between 1/3 and 1/4 what the school’s official NPC was and is still showing you, and you are confident that all the data you provided/entered is correct, I would bring this up with a school FA officer. That’s a huge discrepancy, and not something I would expect to see when dealing with a “top 10 school” that promises to meet 100% of need.
Edited to add: this all assumes that the NPC figure is fairly large (like $10,000 or more), and therefore a 66% to 75% reduction in actual aid offered is a big deal. If the NPC figure is $4,000 and the actual aid offer is $1,000, well, that’s not a big deal.
