Community Service Letter For Students Could I Transfer To Columbia University?

Could I transfer to Columbia University? - community service letter for students

I am a student at a community college and have a 3.8 GPA, I am involved in several EC, including students and the service book club community. Initially I performed poorly in my school, but they have since started to work hard and get those classes. I am now in a society that honors college and have a letter of recommendation from a Columbia graduate who taught at the university, I have never taken a SAT or ACT. What are the chances?
