Chances? Will chance back!

<p>Applying to the following RD (CompSci/Engineering):
Brown, Columbia, Duke, Tufts, Michigan, Northwestern, USC, BU, Illinois, NYU, and Umass (in-state)</p>

<p>GPA: 3.81 UW, 4.5 W(not reported though)
Rank: 45/350 --> this is unweighted, no weight AT ALL to APs and Honors classes, I've took the hardest course load and all that. My school is competitive, 15-25 students to Ivies/T-20 schools each year out of ~350 students
SAT: 2290 (780M, 760CR, 750W)
SAT II: 800 Math 2 and Physics</p>

<p>Alright, with ECs I won't go into much detail, but basically I'm interest in robotics. I've spent the last two years at a university lab doing research related to robotics/CS(bulk of my time outside of school, lol). I've been published, how much does that help? Some ECs as well, such sports, clubs, but robotics has been the main focus.</p>
