I think that you have a really great chance! Mostly because your extracurriculars seem super genuine. GPA is below average but WHO CARES it is only one factor out of many. You did very well on your DAT and it seems like you made attempts to be involved and become more worldly! Shout out to my fellow resident assistant! Make sure to write a killer essay and excellent/mature/knowledgable blurbs about all of your experiences. I would add in Midwestern AZ.
