Will I get rejected from Iowa State?

Iowa State is my top choice but I am nervous I wont get in. I have an 18 ACT and a 2.59 GPA

Have you calculated your RAI score? Depending on your class rank and the courses you took, you might be fine. https://www.admissions.iastate.edu/freshman/requirements.php

Update
So I ended up getting rejected but I’ve been accepted into Ferris state which tuition wise is a much smarter choice and Ferris has made many chances to get to know me before I even step foot onto their campus
