How will dropping out of IB English 12 affect my admissions?

I am applying to basically all the UCs(except Berkeley,Merced,Riverside, San Francisco, and UCLA) and my top choice is UCSD. For CSUs I am applying to CSU Pomona, CSU San Luis Obispo, CSU Long Beach, and San Jose State University.I am applying to USD and Santa Clara for privates. If my UC GPA is 3.8 and have a 1620 SAT score(already a narrow chance of getting into UCSD b/c of this) will it affect my college admissions negatively?

Talk to your guidance counselor but yes, it could have a negative impact on admissions. My friend’s D wanted to drop an AP after she was accepted ED and the college said that if she dropped the AP they would re-evaluate her ED acceptance so she got a tutor, worked hard, and finished the AP class so as not to jeopardize her ED acceptance.
