I am a USC alumna. I pledged
GFB way way way way back in 1975! (A very long time ago!) But rush is still very competitive and now that I live in the south and have seen a few rushes down here, I can honestly say there are many similarities! Chloe173 is a current ADPi at USC and has posted her personal observations about rush there...you could put her name in the GC search engine and see her comments. I also suggest you start trying to get recommendations now if you can.
Edited to add: I saw on some other posts you made that you were going to NYU and another seemed to indicate you were going to UW Madison or UIndiana Bloomington. Did not see a mention of USC....I am confused!
