Intended major on application

<p>two questions: </p>

<li><p>How much does the school within a college you apply to affect admissions (for example engineering at a competitive school like Cornell, UCB, or Carnegie Mellon)?</p></li>
<li><p>How much does the actual major within the school you indicate affect admissions at a place like UCB where they make you indicate a single major?.. just wondering because at most schools you don’t actually declare a major until you sophomore or junior year.</p></li>
