[UCB]Is Undeclared under College of Letters and Science easier to get in than Computer Science (BA)?

Hello!

Both two options are under College of Letters and Science

Berkeley said on the website that all applicants applying for L&S are considered undeclared, while the majors they choose are only “indicative”. I am not pretty sure. Does it mean that Computer Science BA, Math, and Undeclared under L&S are equally possible? Is Computer Science BA a safest choice for a prospective computer student?
