Chances of acceptance

Hello all. I’m from Ohio but I’m moving to Austin TX this summer because of my dads job. I’m enrolled in an university right now but since I missed the deadline to apply for UT Austin, I applied to go to the community college down there instead for a semester or two. I’m currently a bio major but I want to change majors to Political Science once I transfer to the community college there. How do you suggest I increase my chances of acceptance before I apply? Like GPA needed, resumé builders, etc. Thanks in advance :slight_smile:
