<li>Hi, I'm applying as a freshman to almost all UC's and USC. I'm not sure what major I want to do yet, so if I apply to College of Arts and Science undecided and later on want to do engineering like bioengineering or chemical engineering, has it been known to be difficult or easy to change majors?</li>

<p>If you want ENGINEERING it’s not advisable to apply for LETTERS OF ART AND SCIENCE because they’re two separate colleges at the UC’s… FYI. I’m not sure about USC though!</p>
