Chances of getting into Purdue's Aerospace Engineering?

<p>STATS</p>

<p>ACT = 28 (25 on math, 26 on science)
GPA = 3.2/4
class rank = top 60% I know it sucks i was a C student for freshmen and half of soph year
I have an excellent essay I formed with my teacher. I have an upward grade trend. C's freshmen year. Almost all A's junior year. Ive had a job for two years, and have gotten promoted from bagging to working in backroom. If it matters, I want to join AFROTC, and might be joining the civil air patrol soon. Since ive been hearing letters of reccomendation dont matter these days i wont bother getting any.</p>

<p>I know I can get into Iowa State Universities engineering programming, but I would love to get into purdues. </p>

<p>I have no idea why my class rank is so terrible. I guess its because of my freshman year grades.</p>

<p>Will I be able to send in some of my senior year grades (which would get me a slightly higher gpa and class rank) before they tell me im accpeted or rejected? thanks.</p>

<p>I should also add I go to a pretty reputable school, John Hersey High School. according to US News & World Report, my highschool was one of the top 30 high schools in my state.</p>

<p>bump please help me</p>
