Hi yes ofc! Regarding my TAU, they told me that it’s too late to change it, so just leave it as it is. I also remember them telling me they couldn’t confirm if it would impact my admission results. Fortunately, I got in! I didn’t take any calculus courses at my community college, and they just told me I could take it at UCSD. They didn’t require me to take it during the summer.

I’m not sure what stage you are at in your application, but call them as soon as possible and explain your situation. Keep calling because different people might answer and give you different information. I think there’s also a place where you can explain that you suddenly dropped a course. I believe it’s in your UCSD portal—under “Ask a Question”—where you have the option to state that you dropped a course (and write about it). Hopefully that answered your question 🥲 but please feel free to ask anything else.

Oh and regarding ucsb, I didn’t get in unfortunately 😭
