Will a C in my Junior year affect my chances of going to a UC?

So this is what my junior year schedule looked like, including my first and second semester grades.

AP Lang A/A
Spanish 3 A/A
AP Bio A/A
AP Calc BC A/A
Honors US History A/C
Internship program A/A

My UC GPA not including my second semester grades was a 4.4, and my unweighted was a 3.9. I am also a CA resident.

My score on the redesigned SAT is 1390, but I am retaking it.

Just based on my grades and ignoring my ECs (which are average), what are my chances at UCLA, UCSD, and UCB as a STEM major?

Thanks

UC GPA including 2nd semester grades? How many AP/Honors classes 10-11th? What are you taking Senior year?
EC’s?
UCSD looks possible. UCLA and UCB are always a tough admit but a decent chance. One C will not kill your chances. Write outstanding essays you could bump up your chances.

You still need some solid Match and safety schools on your list.

Good Luck.
