Drop AP Chem or not? C- Grade

I got really distracted Sophmore first semester and have a 2.8 to 3.0 Sophmore GPA. (3.8 GPA freshmen year) I got a C- in AP chem and was wondering if I should drop/withdraw it so I can get a 4.0 for 2nd semester Sophmore year. My goal is to get into University of Washington. I do not think I can score well on the AP chem test and the end of the school year. I am taking precalc and standard other classes.

Additionally, how would this affect college admission. I am currently in California

At my dd’s high school, that would have been a mandatory dropping to honors chem. I would talk to both your teacher and guidance counselor about your options.

Talk to your chem teacher and guidance counselor. The policy on dropping a class or dropping down levels of a class mid-year will vary from HS to HS. If you want to drop the class be sure to understand how it will appear on your transcript.
