3yr llb after cs

I am currently cs executive registered student and gonna take up my exam on Dec 2015 both the modules . Can I do 3yr llb after cs executive??? In case if not possible , then if I do bcom with majors in corporate affairs and administration in igou ( due to icsi-ignou tie up I will get a exemption of 2yrs n can finish n get the degree in minimum period of 1yr ) will I get admission in 3yr llb course???? Or in case if I complete cs fully will I get admission in 3yr llb ???? Thanking u !
