<p>i applied as undecided for all and was rejected from UCD and UCSB but not Irvine! ha</p>
<p>To say Irvine or Davis is better in all cases for all students is ridiculous. You must research about your major choice. Additionally you MUST visit. There is no way to know what you will prefer until you have actually been there and experienced it for yourself. I have been to both and IMHO UCD>UCI BUT that is MY opinion.</p>
