UIUC Engineering Undergrad gpa

<p>So I'm a freshman in aerospace engineering and first semester grades gpa came out today. Because of a B in rhet 105 I have a 3.6 gpa currently. What is considered a good gpa for uiuc engineering? I'm hoping to go to good grad school after I graduate and obviously it's gonna get a lot harder. Is 3.5+ really that good?</p>
