Do request a reassessment from UConn after checking everything.
All in all though, this year should be fine if you work and take on a loan.
Calculate what you’d get (FAFSA EFC PLUS UCOnn NPC) with your sibling in college: does that change anything for Pell? For Uconn?
If not, you may have to commute starting you 2nd year - but the transition year of being a freshman in the dorms would be done.
