<p>I think you have it wrong. </p>
<p>UCs will take a maximum of 90 UC-transferable semester units (minimum of 60 I believe) from your CC. Anything above 90 doesn’t get calculated. 90 semester units = 135 quarter units. So theoretically, you only need 45 UC quarter units to graduate. However, that will never happen in practice because your CC won’t offer the necessary upper-division courses to graduate.</p>
<p>Take me for example: I have well above 90 units, but they’re all from a CC so it doesn’t matter. UCSD is only taking 90 of them. I need approximately 65 quarter units worth of classes for my major in order to graduate. 90 semester = 135 quarter, + 65 upper division for my major = 200 units. </p>
<p>Now, if you go for the minimum at CC and transfer with 60 units, you’ll get to UC with 90 quarter units, and the minimum needed to gradate is 180. So this way, you’ll need to get 90 at your UC to fulfill the requirements. 15 units a quarter x 3 quarters a year = 45 units x 2 years = 90 units + 90 previous from CC = 180 :)</p>
