That has got to be a new rule. Because even in my Senior year, every house was accepting sophmores and quite a few even juniors. It was something like, Juniors and Seniors didint count for towards total. They were considered freebies. But most houses didnt take them beacuse they felt they didnt have that much time to contribute.
Designergal is right thought when she says MANY of the popular houses have high de-active rates though.
Either way, go in thinking with an open and positive attitude for all the houses. Reps, where good or bad can be misleading. Think friends for life, not for an hour. GO BLUE!
