Impact of competition success(specifically Siemens, Intel STS, AMD or like calibur)

<p>I was wondering how much of an impact receiving a regional finalist/semifinalist honor or even placing nationaly, could have on one's chances at Ivy League Schools. Do they rank in the "Outstanding EC" category? Can they save an otherwise lacking EC application? I have heard placing 1st or 2nd, in a competition like Siemens Westinghouse or Intel STS is almost an auto-admit, given probable congruitiy of success in school. Any merit to this rumor?
The reason I ask is because I'm currently working on a breakthrough scientific project which I will submit to all these competitions. I believe I have a chance at top honors or at least regional awards. Any help is appreciated!</p>

<p>It helps a lot, I think. Being a semifinalist in STS and SW is amazing. </p>

<p>Being a Finalist is even better. It definitely helps in the admission process. But, once again, nothing is guaranteed. Most STS Finalists go to HYPSM.</p>
