re: Student Loan Planning/Strategy

Paying off B first is both psychological and tangible. When you get B paid off, you feel the win, but also you have one less minimum payment to worry about. Your momentum then rolls into the other loans. It makes sense, but it works better for someone who REALLY wants to be done with debt. If you're looking for ways to have the loans be "manageable" over the long term, then the snowball may not be your best bet. You'd be better off concentrating on deductions and refinancing to save interest.
