Hello Bhaskar!

You can opt for 3 year law programme or 5 year law course. You have to give Entrance Exam for most of the colleges such as CLAT, AILET,LSAT. And on the basis of merit you can get admission. 

But there are some colleges which give admission on the basis of the 12th result. 

Search according to your interest. If you have any other question you may please ask.

All the best. Thankyou
