Qs about units and GE requirements

<p>Ok, i have 12 units from the AP exams, and I'm required to have at least 184 in order to graduate. I'm just wondering, how many units (at least) do i have to take at UCSB? 172 or 184? </p>

<p>also (i dont wanna start another thread), if i'm taking a certain course just to meet one of the GE requirements (doesn't apply to my major), can I take it for n/np or must it be letter-graded?</p>

<p>thanks</p>

<p>i think units are major-specific</p>
