Hello Risalat, See after graduation you can take 3yrs for LLB.

Law Types: BA LLB (5yrs course - for those who recently passed 12th board) and LLB (3yrs course - for those who completed their graduation in any field)

For further query be free to contact... All the best

Hey Risalat.

The duration for LL.B is 3 years. If you apply directly after completing your B.A., you can complete your LL.B course in 3 years after BA. There also an option of 5 year law. But this is not advisable after BA. 

Hope this helps you. All the best.
