Are your finances complicated? Divorced parents, small business ownership, rental properties, and trusts can all throw off the NPC results. You likely won’t get as much aid as is shown if you have one or more of those.
You can ask if they will do an early FA read, not sure but it can’t hurt to ask.
How do the NPCs look at other similar colleges that meet need? Say, Amherst, Carleton, and Williams? Are you clear on loans vs grants in the results, too?
