Bad grades first semester of junior year?

Freshman year my grades were decent, a’s and b’s, sophomore year they slightly improved first semester but then became more steady with my freshmen grades again at the end of the semester, but junior year i got a d+ in honors precalc and a c in AP english lit, and a c in honors physics. My GPA is a 3.1 and a 3.8 weighted. I’m doing better second semester, no c’s, but i’m really worried. Can I get into a UC school or any good school?

It could be possible to get into a competitive university if you score high on the SAT and do better this semester. That being said is your GPA culimative or 1st semester junior year? The best option however would be doing junior college then transfer if your goal is to attend competitive colleges like UC"s.
