What the heck kind of medical program can you get into with a 2.26 GPA???
I am pretty doubtful that you would have a successful recruitment with that GPA- you are a major grade risk. Even if they loved you oodles and oodles, your grades are close to failing out of school.
Stop worrying about whether or not to be greek and get your grades together so you can get a job or get into grad school when you graduate.
