UC GPA Calculation

<p>Hi, could someone explain to me how is GPA calculated for UCs?</p>

<p>I know they look at 10-11th A-G subjects grades but how should they be calculated?</p>

<p>I heard there are four different variants (unweighted, weighted, uncapped, capped), what are the differences among those and which one does the UC use for freshmen applicants?</p>

<p>Thanks.</p>
