In the days of liability and lawsuits, many if not most of the NPC and NIC fraternities have strict rules against drinking and yes, on many campuses, both sorority and fraternity houses are dry. That began to change while I was in school, dare I say it, 25 years ago. That REALLY depends on the campus. Some are decidedly NOT dry and even still include alcohol in rush events, a HUGE no-no on my campus (and I think probably most).

Tiers is kind of a dirty word that describes the social ladder in Greek life. You have the top tier houses (spoiler alert: I'm using generalization and stereotype here!) that are the most sought after, the best looking, the most money, etc. Then you've got the middle where the houses do just fine, get the members they want but maybe not ALL of the members they want, are financially stable, etc. And then you have the bottom tier houses that can't get the members, are the least attractive, have the ugliest house in the worst condition (this applies to fraternities only - even sororities that struggle maintain their houses). On some campuses these rankings are fixed in stone and being in the RIGHT house is everything. On many campuses those tiers are subject to interpretation. This is virtually the entire plot of Revenge of the Nerds. In fact, it's the primary story line of almost any movie or TV show about Greek life.

If you read through the sorority recruitment stories, if you can read between the lines you can see these tiers described over and over again. "I just couldn't see myself fitting in with these girls" is code for "they're the bottom tier."
