Getting classes as a transfer student

<p>Ok here's my situation:</p>

<p>I am currently enrolled in a 4-year private university.</p>

<p>I plan on leaving the university to attend a community college for a year to save money.</p>

<p>I then plan on transferring to UCLA.</p>

<p>My question is: Will I have trouble getting the classes I need once I get in to UCLA in order to graduate on time? I hear it's really hard to get classes right now.</p>
