<p>I heard that you can only apply to 4 University of California schools. Is this true?</p>
<p>From what I understand you can apply to as many as you'd like.</p>
<p>No, you can apply to as many of the UCs as you want. What you are talking about is the fee waiver. If you qualify for it, then you are allowed only 4 FREE UCs. The rest, if you're applying to more than four, you have to pay.</p>
