WILL ONE C IMPACT MY CHANCES OF GOING TO A TOP UC???

I’m currently a junior and my first semester is almost done. I recevied a C in AP BC Calculus.
This is my first C and i also have 3 Bs on my 10-11 transcript so far while the rest are all As.
Want to have engineering as my major in good UC (Berkeley, LA, Davis, San Diego, Irvine and maybe even Santa Barbara).

Ranked top 10
On the swim team.
I have 300 community service hours.
In CSF, Robotics, and Science Olympiad for clubs.
Also in a special Space and Engineering Acasdemy offered at my school.

Estimated to have 4.31 10-12 weighted GPA by the end of my junior year.
3.73 unweighted 10-12 GPA.

How bad would a C affect my chances of going to a good UC?

Also got a 1930 on SAT( 740 Math, 560 CR, 630 Writing)
Took one AP test so far for AP World History and got a 3.

Yeah, I’d also like to know how much a C in Calc BC will impact an applicant’s chances. I’m a senior taking the course and I’m in the same position…

What’s your UC weighted gpa?

4.13

Look at the admitted student profile for each campus and compare your UW GPA and SAT
scores:

With a 4.3 and 1930, you’ll likely get into UCI and UCSB engineering. UCSD is a maybe, but UCB/UCLA are unlikely.
