Asian American Race to get into a Top CS Program

@ucbalumnus would you say the bottom half of the UC’s are considered safeties? What about for EECS, CSE, CS? Also, is CS (not EECS or CSE) impacted at the mid tier UC’s and UCSD/UCLA? Which
major would be the easiest to get at these?

And if I was admitted undeclared at SD/LA, would getting a 3.9+ get me my major? I know it was like this a few years ago, but I still don’t get the whole lottery thing. Is it actually random?
