Average SAT/ACT scores, but high GPA?

<p>Is this normal? I have a pretty good GPA, around an 3.8. I am ranked in the top 5% of my class… Do you think a 27 on the ACT and 1800 on the SAT would make my grades look bad?</p>

<p>Im also planning on attending UT Austin… I know they auto admit top 9% (for class 2012). Would my test scores have any effect on this?</p>
