You will form your own opinions based on your rush experience. Don't worry about what other people say or what stereotypes there are. Keep your grades up (don't let senioritis affect your GPA), get your recs in order next spring/early summer (for all chapters if possible), have fun shopping for your white dress for Bid Day and your other recruitment outfits, and don't stress about KY greek life until next year.
Don't have the attitude of "I know I'm supposed to have an open mind, but...." REALLY keep an open mind and heart.
