2collegewego,
Yes, I heard about that too. I have been asking that question (NPC vs. the actual aid) in a few posts. People complain about the actual aid being too low. But, not too many are interested in sharing the actual numbers and circumstances. I think that posters are just not comfortable disclosing the info. The simple format can be like this:
School:
NPC= X (Student + parent)
Actual EFC = X+Y
Actually, this may not be a bad idea for USNWR to rank the schools based upon NPC accuracy.

For now, I have set the maximum EFC based upon each school's NPC calculator to narrow down DS3's application. If he can get in any, I will have to check with the schools to find out the EFCs for all 4 years. And, I will be happy to share.
