Is it too late to apply to another UC?

<p>I already applied to UCB and UCLA, but I suddenly also want to be considered at UCSD. Is it too late to send them the check with a letter?</p>

<p>UCSD is closed. Here is the link to ucop website with info on campuses that are currently taking applications for selected programs
