<p>Hi, I’m still new to this site so I’m not too sure if this is the correct location but
does anyone know if any of the UCs require supplements?</p>
<p>Nope, UCs do not require supplements. Only private colleges associated with the Common App do.</p>
<p>If by “supplements” you mean extra letters of rec, extra essays, a resume–then no. However, you do need to send in your official test scores.</p>
