There is no right or wrong to do LLB after graduation (be it any course). Before the launch of the 5 years B.A-LLB programs at NLU, most of the students used to pursue law only after graduation. Even now students who missed out on opting law post class 12th plan to take it up after graduation. And it's okay to take LLB even post your eco hons. But the larger question to ask is whether you are passionate for legal studies as a career or not? Are you the one who can be in books throughout your life, do you have investigative interest and ready to take up a challenging career options which usually take time to build up ? Do you have high reasoning aptitude/problem solving aptitude? If your answers are yes to these questions, LLB can be good for you.
