Waitlisting???

A few questions about waitlisting?
I accepted the waitlist to Stony Brook however if i do get in may i be able to rescind my descision or would that be too late? Should I see if I can rescind my decision now?
because i had accepted it at first because my parents do not feel totally comfortable of me going to university of buffalo but now they’re okay with it? (i dont understand parents sometimes and I think they still want me to go to stony tho… )
I can’t decide between the two of the schools but i have already accepted the waitlist to stony
I am also told that I have to deposit to another school after accepting a waitlist to another school. I also have to pay for housing as well for UB too though. after depositing and getting accepted to my waitlisted school, will i have also have to pay stony’s deposit and housing fee as well?
(I am going to the psychology major and planning on going to grad school btw)

Being on the wait list doesn’t commit you to going if they offer. If they want you off the wait list, they’ll offer you a spot, which you will be free to accept or reject.

In the meantime, there’s no telling if you’ll get an offer from the waitlist, so you should definitely put down a deposit at another school, so you don’t find yourself with no school to attend in September.
