Help! MS in Finance chances? Pre-med background

I graduated from a top-20 ranked university with a 3.3 GPA but did a post-bacc to make my overall undergrad GPA a 3.5. I have a pre-med background and no professional work experience.

I’m currently enrolled in a Physician Assistant master’s program but have realized that I find finance more interesting. What are my chances of getting accepted into any MS in Finance program? What about at Texas A&M, University of Houston, or UT Austin?
