Does University of Texas at Austin look at just your senior transcript or also your senior for rank?

I’m graduating in the class of 2019 and my junior transcript comes to a close 6.4% rank of the overall school. I’m guaranteed to bring it up way above top 6% by the end of my senior year or even the beginning of my second semester. Will the office of admissions acknowledge this whatsoever, or throw me in the discard pile? (Am pursuing in chemical engineering)
