Are the grade 12 high school requirements for Comp Sci BA and Bsc the same or no?

Currently doing couse selection for Grade 12 and I was wondering if the grade 12 high school requirements for Computer Science BA Degree and Bsc degree the same or no? If I want to apply for the BA degree would I need to take grade 12 sciences since I'd be taking Liberal Arts courses and not science courses (BSc Degree) as complimentary courses? Any help would be appreciated thanks!
