<p>A couple of important things not mentioned by previous posters:</p>
<p>(1) Only courses taken during the sophomore and junior years count in computing the UC GPA.</p>
<p>(2) Courses like "Health" and PE don't count at all--you just throw them out. The courses that count are the a-g courses given at the link provided by jaynele above</p>
<p>(3) There is a cap of 8 GPA points added for the first 8 semesters of honors/AP/IB courses taken during the sophomore and junior years. Any other honors taken don't count for "extra" grade points (you still get the standard grade points A=4, B=3, C=2, etc.).</p>
<p>(4) Not all "honors" courses count as such. You need to look up your high school on the UCOP "Pathways" website, where it tells which courses count as "UC honors" and which ones don't (this is only for California high schools, if you are in a different state I don't know how they know which should be honors and which shouldn't).</p>
<p>(5) You get +1 point added for UC honors, AP, and IB courses up to the 8 course maximum. After that you get nothing (nothing extra, that is).</p>
<p>(6) Taking more courses and getting "A"s in them once you reach the 8 course cap will actually lower your GPA if you are above a 4.0 UC GPA at that point--but the UC admins take this into account since they want people to take more courses, not less.</p>
<p>For the person above, the total is 10 As (worth 4 x 10 or 40) plus 10 Bs (worth 3 x 10 or 30) plus 8 extra for the honors/AP courses gives 78 total grade points divided by 20 courses or a "UC GPA" of 3.9 </p>
<p>There is no such thing as a UW or W "UC GPA", just a "UC GPA"</p>
<p>UW GPA would mean all the classes added up together divided by courses attempted with no extra points for honors. A weighted GPA would mean adding up all the classes using one point extra for each honors/AP/IB courses taken then dividing by the number of courses attempted. In this person's case, the UW GPA would be lower than the UC GPA, but the weighted GPA would be higher than the UC GPA for the sophomore and junior years (but probably lower once you added in the freshman year).</p>
<p>A final note: Not knowing this person's SAT scores, I would estimate them as a Reach for UC Berkeley and UCLA, a Slight Reach for UCSD, a Match for UCSB/UCD/UCI, a Safe Match for UCSC/UCR, and a Safety at UCM.</p>
<p>This is presuming they have around a SAT score of 1850. Higher or lower SAT scores would change that assessment.</p>
<p>Your chances will also depend on other things like: Did parents go to college?, Are you from a lower-income family?, Are your parents divorced and you live with just one of them?, and Do you have a unique skill in music or athletics? etc.</p>
