<p>If it's any consolation, as evidenced by CC itself, doing well in these competitions isn't going to guarantee you anything in the college admissions process.</p>
<p>Semifinalist status - sure, a student could manage to take a PhD's work. But first she'll have to put in extra effort to meet page-length requirements, try to decide what's important, switch formats to meet demands layed out by Intel or Siemens.</p>
<p>All for something that colleges won't put so much consideration into unless you have the scientific gung-ho and know-how in other ECs to prove that you deserved it.</p>
<p>As for a Finalist spot, again, easy to borrow professional work. But by this point, you will have to make a presentation. You will be bombarded with questions from experts of your field to test the depth of your knowledge.</p>
<p>And as is evident in people who do steal work, you'll never get a complete understanding of what you do unless you get full-blown experience in either doing the research or discussing the details with your mentor (the latter of which should compel you to participate fully in working on the project anyways.)</p>
<p>Memorization is not easy for such in-depth things like these. As if recalling a perfect answer like "This response is markedly attenuated by coexpression with the Bax antagonist antiapoptotic protein Bcl2, confirming proteolytic activation of caspase-3 in these cells." to a question is possible when you have no idea what it means.</p>
<p>And in these competitions, who knows if they won't decide to humiliate you on a national level for cheating your way to the top?!</p>
<p>Anyways, what I'm saying is that of course there can be people who get on by for a time relying on non-original material, but you shouldn't assume the entire competition is crap because of the -possibility- of people doing this. If you look even only at Finalists and not even at Winners, they all have incredible credentials and put in time-consuming (original!) research, and, in the end, that's why they've been rewarded top prizes.</p>
