Well the first thing you want to accept is any scholorships and grants since you don't have to pay them back. Well unless junior fails or drops classes, my oldest did that. :(
Then the next best is the Stafford sub which does not accumulate interest while the child is in school. Then the Stafford unsub and Perkins which do accumulate interest even when the child is in school. There is little difference between my Stafford unsubs and Perkins interest rates.
So then private loans, lord have mercy, I have some rather crass comments about them I will not share but avoid them like the plague. You can usually qualify for the parent loan which shares a lot with the Perkins and Stafford unsubs.
