<p>Keep into account also that UCSB may have the 3rd most applicatns in the UC system because it is a backup school for many people. I think it is probably most people's backup school since it only has a 20% yield (out of all the people that get accepted, only 20% actually enroll). For comparison, Berkeley and UCLA have 45% yield and schools like Harvard often have upwards of 80% yield.</p>
