Law

IGNOU doesn't offer LLB programme affiliated to BCI. In Delhi NCR region good institutes like DU and Amity University offer LLB programme affiliated to BCI.

Around 20,000/- rupees.

Yes, its good to pursue a 3 years course for corporate job. Don't waste your time for a 5 years course. If you are interested in work to corporate, go for a 3 year LLB and you can go for side by side. Do internship in law firm correspondingly.

It depends on your institute and then your CV basically.
A law school graduate from any National Law university having a good CV easily manages to get between 50000-80000.p.m. if get placed in top law firms.

You can get a specialisation in Corporate law or rather, you can do your LLM in that.
Simply doing LLB won't help these days because corporate firms give more weight-age to graduates from National Law Universities these days rather than traditional universities.

Hello Ketaki,
Normally in college, you can select only one graduation course. You won't get admission in another. However if you are really interested and willing to put in hard work, I suggest you look in for various courses offered by IGNOU. wide variety of courses are possible here.
