Dear Bhanu,
The Tamil Nadu Dr. Ambedkar Law University offers students direct admission in BALLB programmes on the basis of marks obtained in class 12 th .

Guru Nanak Dev University’s Faculty of Law could be another option for you.
There is another good option for you, The University of Calcutta will conduct Calcutta University BA LLB 2018 Entrance Exam . Application process will begin very soon.
By the way Going by your marks obtained in 12 th , it can easily be guessed that you are a bright student. There is a saying, ‘no pain, no gain!’ If somebody is interested in doing 5 year integrated LLB, ideally he/she must go for CLAT which gives the entry pass to top National Law Universities. But you are looking for easy option i.e. entry in Law programme without going through an entrance test. I think you are afraid of loosing one precious year, but believe me it’s worth dropping a year and preparing for top notch Law institutes which are considered at par with IIMs, IITs.
I hope it helps!
