LLB

It depends on what you want to do, if you want to do law you will have to do a 3 year law course, then you can do a job, in pvt. firm or government job or start your own practice, whatever suits you. You must be more experienced as you have been working for 3 years.

Kindly check the syllabus online for the entrance exam. However work hard on general awareness questions.

Hi
First of all, you have to do a 3 year LL.B. from DU/CCSU/JMI etc. Then you can do Masters in corporate law from NLUD, DU, ILI, AMU, JMI etc.

Hi
The answer would be based on your interest areas and long term career plans. Both the career are good. MBA done from a good college is a headstart but a career in LLB can be slow. Since you will appear for government exam, do law as it gives you power and authority, but remember that promotions may not be that fast.

Please check the brochure of the college and prospectus of the college to get exact information about the timings and courses offered.

Hi
While no strong yes or no can be given, it depends on you to make it worthy. Studying law is not only ltd. to classrooms, you have to get out and do internships as well and since Delhi has all the courts and major companies and firms it is tremendous benefit. Furthermore, there are many other law colleges and universities from which you can pursue certificate courses to boost CV. These advantages are not available in Odisha and many aspirants from your state come to Delhi. But at the same time the radical environment in JMI cannot be ignored. So you have to see it for yourself.
