Didn't get enough Financial Aid - Do Extenuating Circumstances Letters Work?

So here we are: Colleges accepted daughter. One is more expensive than the other, and daughter could succeed in both, but wants to try to gt more financal aid from them - to make it more comparable to the other.

What are the chances the school does something to get her more financial aid?

Thanks!

Some schools will accept appeals for more financial aid, but you have not provided nearly enough information for anyone here to estimate your “chance” of this happening for your particular situation.

What are the two schools?

What specific aid (type and dollar amount) has each school offered?

What “extenuating circumstances” are you faced with?
