Several questions regarding UC admission

<p>freshmen applicants:</p>

<ol>
<li>When you apply in College of Letters and Science, no matter what major you chose, everyone comes in undeclared. The first day you start a UC as a freshman, your major will be Undeclared-YourMajorHere. Then you will get to choose the real major in your soph year......</li>
</ol>

<p>Is this true? Then undecided is a good choice within college of L&S</p>

<ol>
<li>Undeclared is supposedly a good idea for UCLA, although not the best idea for Irvine......</li>
</ol>

<p>Someone posted this. Is this true? Why?</p>

<ol>
<li>Someone said.......As freshman, switching your "declared" major is no problem, I had a friend switch from women's studies to engineering at UCI, before he even started there, he called two weeks after he got his acceptance letter and they let him....</li>
</ol>

<p>Isn't engineering is more competitive and more difficult to get in? Why did the university let a student switch from an easier major to an impacted major right away? Is this true? Wouldn't this hurt other applicants who pick engineering as their first choice in the applications?</p>

<ol>
<li>If I go undeclared when apply, how hard it is to go from undeclared (or other majors in L&S) to engineering? In soph year. How big is the chance? I heard that it's possible.</li>
