6% rankings

Hello, I’m a freshman and our ranks just came out. I’m hoping to study engineering at UT and I live in Texas, so if I’m in the top 6% of my class I can get auto admission. With our recent ranks I ranked 42/567 which isn’t amazing, and I’m pretty sure it’s like top 7-8%. I have 4.0 UW GPA and 5.06 weighted (6.0 scale). I was wondering if the top 6% auto admission applies to all 4 years of high school or just your junior and senior years.
