UCLA Alumni? help!

<p>Hi!
I am attending UCLA Fall 2014.</p>

<p>1)Does UCLA have a core curriculum, one like UChicago that has a bunch of requirements?</p>

<p>2) In regards to dorms,
I am made to choose three options, and order them in order of my preferences.
I want the cheapest dorm, which is the residential halls.
I HAVE to choose the other options too as my backup.
Does that mean I may have to pay more for my dorming if they can’t get me the basic res hall that I asked for?</p>

<p>Thank you!</p>
