how can i take less than 12 units and pay less money than a usual quarter?

<p>i know it’s possible but i’m trying to find information on it
i read somewhere on this article by a UCSB student that he only took one class his last quarter, and paid less for it, per unit i think, but i don’t know where it went. if you have any information about what this is called, it would be greatly appreciated thank you</p>
