Is it worth applying to SSA scholarships?

Are both kids going to the same school in IU? It looks like some of the schools use the SSA, like Computing, and others do not, like Kelley.

We have been pretty impressed with IU, but do find these sorts of things unsettling as we consider the place. Given the size of IU and how much goes on there, I worry that the system may be hard to navigate. It is not made better by this sort of unclear stuff that leaves you with this unsettled feeling that maybe you missed something that others were somehow informed about.
