UC Transfer Essay(Required Prompt) Different Majors?

Hello, I’m a computer science major who’s also very interested in mathematics. I’m applying to most UCs as a CS major w/ Mathematics as my alternative major. For Berkeley, I’m missing the Data Structures class so I think my admission chance would be very low if I apply w/ that class missing. I see that I fulfill all the requirements for Math so I’m thinking of applying as a Math major.

I have a question regarding the required question for UC essay, if I’m applying to different majors for different schools and I only get one essay sent to all the schools, should I specify that I’m a CS or Math major or should I just write my major vaguely or incorporate both? Thanks!

I’m applying for business administration and economics, but more economics than business. So, I decided to talk about economics more than business. Im not 100% sure how they look at it, but since you’re applying as a CS major for the majority of the UCs, I would talk more about CS
