Chances, will chances back...

<p>Applying RD to following schools:
Brown, Duke, UVA, Michigan, Northwestern, UChicago, JHU, Tufts, CMU, Cornell, NYU, BU, GeorgiaTech, UT-Austin, Illinois, and UMass </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: 2260 (780M, 730CR, 750W)</p>

<p>Alright, with ECs I won't go into much detail, but basically I'm interest in robotics/engineering. 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 other ECs as well, such sports and a few clubs, but the aforementioned has been the main focus. Will class rank kill my app?</p>
