Applying Undecided/Not to UC's

<p>Hi,</p>

<p>I was wondering whether it is better to apply to the competetive UC's (UCLA, UCB) as an Undecided Major, or not. I am thinking about applying to both as a "Persian Studies" Major. I assume that this major has a higher acceptance rate than most. If I were accepted to UCLA like this, could I 'easily' change my major to Neuroscience after I got there?</p>
