Jessica, I cosign with what everyone else has said. Also, remember during FR "rules" are very different than during COR/COB. For example, during FR a house might have to drop girls who don't have a 3.0 but during COR/COB they might be willing to accept girls who have a 2.5 (if that makes sense).
I say, if you really felt like those houses were meant for you, keep your eyes and ears open for events. Informal recruitment is much more laid back.
