Hello Saket Kumar!
I am glad that you have a question for us. Secondly I am happy that you are interested in purusing law. Now coming straightaway to your query, Institute of Law, Nirma University accepts CLAT scores for its admissions. Last year, the last rank to be admitted officially was 2570 and in 2016 it was around 2300.
I am not sure about the exact score but it could be at least 125.
And for this your preparation needs to be strategic and properly planned as you will be competing against 40,000 other law aspirants like you.
All the best!
Keep questioning as it's a good habit and will help you in learning what you haven't known!
Hope to get further queries from you soon.
