Got it. I would start the appeal process with Harvard ASAP.
Is there anything obvious that may have been input incorrectly, or left out when you ran NPCs e.g, all assets, all parental and student income, etc.?
Some typical issues may arise where parents are divorced, not adding back 401K contributions to income, parents who own a business/investment real estate/multiple homes/farms…do any of these apply? Can you compare inputs on the NPC with those on CSS Profile? That will help you as you navigate the process.
