National Law School of India University, Bangalore

Hi Shanmukha, if you're already pursuing Engineering then I'd recommend you to go for 3 year LLB. 5 year LLB is also an option but it's longer and ideal for those who have finished their 10+2 but for graduates, there's a 3-year LLB Programme that they can enroll. It's comprehensive, and you will be eligible to practice law on finishing the Course. The weightage is the same on both the courses. However, for NLU's you have to appear for CLAT and on qualifying the exam you can get admission in one of the NLU's. But CLAT is for 5 year LLB and not for 3 year LLB. So choose wisely. Further, you can go through this article of mine as it answers all your questions when it comes to starting a career in law:
