You have to work with them on housing. I’m sure the $2350 is for a dorm room.
Schools don’t like to write checks for off campus housing. My daughter’s school gave her very generous FA, but did not write checks to vendors, landlords, etc. If she lived on campus, her dorm was covered. Since she lived off campus, nada. Same with insurance. They would not write a check from the school’s funds, so daughter had to pay the insurance from her student loan (billed through school, paid from her loan funds).
You are in an unusual situation for Amherst. You have to check with them.
