Applying to major and honors program at ut

I know I’ll be accepted to ut in 2019 with auto admit but I just heard you have to apply to a major and the honors program so I was wondering how hard is it to be accepted? I’m looking to in physics or astronomy which is college of natural sciences. I have nothing for ecs (well nothing from the past two+ years, potentially some stuff for next summer/school year but it’s up in the air) high gpa, my psat before taking algebra 2 was 1200 and I’ll be graduating with an associates degree with our local dual enrollment…

PS sorry if this is the wrong place to ask i’m new to cc lol

This is a place to ask. If you are in the top 6% for 2019, you are an automatic acceptance to UT. Your SAT/ACT scores will be very important for your admittance to your major as well as ECs and your essays. For admittance to physics/astronomy, I would think you would need a high math score on SAT/ACT and good AP physics and/or AP calculus scores.
