AroundHere, you can’t look at the “average” for low income students. It includes kids with generous packages and kids with crappy or zip.
OP, did you run the NPC/Net Price Calculator before applying? BU doesn’t promise to meet your need. Not at all. It’s not a Meet Full Need college.
“I demanded an answer as to why my financial aid was so low…” Word of advice: no one should demand, start ugly arguments, etc… FA folks are allowed to shut you down, if they perceive rudeness, undue pressure, etc.
Muhlenberg is not Meet Full Need, either, so what they describe doesn’t apply to schools that do offer to meet full need, (based on their own calculation, not just the Fafsa results.) Just pointing that out cuz if it gets pinned, there should be some clarification.
