I hate to say this but…there is an old saying “garbage in, garbage out”. I know you did your best completing the NPC, but do keep in mind…this just might not be accurate for you with divorced parents.
Did you have your parent 2022 tax return to get info when you completed the NPC? And when did you complete it? Some have only recently been updated for the 2024-2025 academic year.
Before you call…run that net price calculator again…and I would suggest only using the sibling in undergrad in addition to yourself.
And remember…you don’t need to have close contact with your dad. You simply need to know where he is…and with a recent divorce, it’s likely your mom knows how to find him.
