How good is Christ Institute of Law at Pune, that is managed by Christ University Bangalore?

The question is not as delicate as it seems to be, so need to highlight few more things i.e. would be answering the second part of your question first i.e. how is law in general, crowd, pressure etc.
But before answering your question,
a small suggestion that preference should be given to National Law Universities, when it comes to pursuing law in India but not in every case and that will be discussed subsequently that when should you choose private law colleges like Christ and Symbiosis over National Law Universities.
So, why National Law Universities? Because one thing is for sure that among other things these universities will surely, provide you quality education, and will focus only on law with a handful of students (between 500 to 600), the student quality would be better i.e. the crowd than these private law colleges.
The biggest trend that is being followed today before choosing a law college is placements and later rest of the things come like the faculty, the infrastructure, location, student teacher ratio etc.
