My daughter is a freshman. Pretty sure the contract is binding. One thing I wasn’t too happy about, was that we were figuring she would get a “standard” sized dorm room - - running roughly $4600 a year. She was put into a larger dorm room that she didn’t want, which was about $6400 a year. By the time we saw the bill, she couldn’t really change rooms. That extra $1800 a year didn’t make me too happy!
Overall she has been really happy at Purdue though!
