I don’t know the answer, but consider this…
even if you’re chosen for QB, when it comes time to apply for aid, those CSS schools are going to be looking at 4 parents’ incomes and assets. When that happens, will the schools likely determine that the 4 parents should pay more than they’re willing to pay? Will your bio dad and stepmom even fill out the paperwork? Will they pay their “fair share”?
If not, then that should be your bigger concern.
