I attended a high school freshmen year in California, but the High School kind of moved away (chater high school) so I moved to another high school in Sophmore year. I finished freshmen year at my old HS started 10th grade at my current HS. So my question is that do I need to send both transcripts from both schools to UC schools even if my current HS has all the academic info from my previous HS (like grades classes and GPA).
You don’t need to send transcripts to UCs, you just report grades for each year and list the high school where you received those grades/took those courses on the UC app. The only case in which you would need to send transcripts to a UC is if you decide to attend at that paticular campus (after you’ve been accepted).
