But federal student loan interest rates aren't low. Undergrads' loan options are determined by their parents' income, regardless of whether their parents are providing financial assistance. Graduate students can't take out subsidized loans at all anymore, even if they are on food stamps.

My loan rates are 6.55%. After 10 years of continuous school, that really, really adds up. I even had scholarships but they wouldn't cover my dorm, the mandatory meal plan, or summer classes so that I could finish undergrad faster. I looked to refinance with 3-4 different companies, like SoFi, but the lowest they offered was around 7% despite my very good credit score.
