<p>When I looked in the course catalog online, I saw that "upper division standing" was one of the prerequisties for all upper division level classes. What does "upper division standing" mean? Is there a minimum number of units you have to have completed before taking upper division classes?</p>
<p>90 units or above. sometimes, this can be waived. restrictions may apply, see dept for details.</p>
<p>it's not for all upper division courses...for example math...</p>
