Hiii aspirant..

IIT Kharagpur is one of the premier institute for pursuing LLM other than the National Law universities in India. I am so far each and every person in India knows the tagline, the placement scenario, the infrastructure, the faculty IIT passout get.

And if we considered the fee structure than the fee for IIT KGP LLM program is about 1.5 lakh per annum which is not much comparatively. Also the institute premium placements when compared to Central University Punjab and since the IIT tagline always work you are never going to regret pursuing LLM from there. The campus life is also very good at the place and far more than that the institute is blessed with rich source of books, journals and a wide range of experienced professors for learning law.

So, I would recommend surely you to go for IIT Kgp instead of CU, Punjab. 

Hope it helps. 

Best of luck for your future.
