<p>UC's don't calculate 12th grade 1st semester into UC GPA? So, they just look at 12fth grade grades to confirm an upward/good trend but that's all?</p>
<p>No, they don't calculate 1st sem.
They just look at 12th grade CLASSES. (I'm not sure if they request a mid-year report though, but if they do, it's just to check if you're doing decent and not getting Ds or something)</p>
<p>^ They don't request a midyear. If you decide to enroll, though, you have to send your final transcript.</p>
<p>Very occasionally they do request a midyear report if your application is on the bubble. They trust you will keep your grades fairly consistant senior year, and will check them after the final marking period if you are accepted. In your acceptance they do spell out exactly what you need to do to hold the acceptance, so it's not much of a mystery what senior grades will cause them to rescind your acceptance.</p>
