Transfer Grants

I am going to be a sophomore this fall 2010 at the University of Florida, and I was looking into transferring to UT in the fall of 2011. I was wondering if UT offers grants or scholarships to out of state transfer students, since the tuition would be huge for me. Not sure if they have grants for students from low income families, or if the offer a out of state tuition waiver to students who have a high enough GPA. Also how competitive is the transfer process (I'm a biology major, if that helps)? At UF they have a rule that if you transfer with a certain major, you cannot change it again, is that the same case at UT?</p>
