CSS profile vs fasfa

<p>I'm filling the css profile on college board for USC requirement. I'm wondering does UCs require te css profile too? Do I have to put the UCs I applied in the college list in the css profile too? And what's the different between FASFA and css profile. Thank you</p>

<p>css is for private schools. so UCs obviously dont use it.</p>

<p>I hate that we hate to pay for this, ughh!</p>

<p>one other thing… Fill out the CSS first because it is crazy in the amount of info needed but then you can just plug in the numbers into the FASFA. You can not plug the FASFA numbers into the CSS.</p>
