UC Berkeley CS Degree-BA or BS?

To declare L&S CS after admission to L&S, here are the requirements according to http://www.eecs.berkeley.edu/csugrad/#petitioning :

It is likely that you need a GPA much higher than 3.0 to get admitted as a transfer student. Once admitted, you must complete the remaining prerequisites with a 3.30 GPA to enter the L&S CS major. Prerequisites previously taken at Berkeley (e.g. in summer sessions) count toward that GPA, but those taken elsewhere do not.
