Is my gpa good enough for rush

Not to be the bearer of bad news but the panhel average is around 3.3 - and the more popular chapters tend to cut higher. You're likely to get dropped by a lot of chapters - especially as rush is competitive. I would focus on your resume and connections, and try to bring your A game during rush itself, and hope your personality shines through enough for people to fight for you. Worst case scenario, if it doesn't go well, focus on getting your GPA up during sem 1 and forming connections then COB.

I would also like to say that all the chapters are great here so please keep an open mind and don't just look at chapters based on "popularity".

You probably will not get into Chi O or G Phi but u will be fine for most other chapters. Most have their recruitment requirement at a 3.0 but if they really like u then it wont be a problem
