Dear aspirant!!



B.com LLB is good course now a days. You must be clear in your mind and then you can add up CA and CS with any of the one degree with it. These both programs are of three years. You can add CA with any of the one program. The choice is yours. From my point of view doing CA other than CS will be the best option. You can do any of them.



Hope your query is solved!



All the best!
