Hello Rajat, 

There are many mock-test series available by different coaching institutes. Instead of focusing on any one coachng institute, try to get a sense of multiple institutes. Maybe you can plan with a friend of yours and take two different test-series and then can exchange with each other. Some of the leading test-series for CLAT are: Career Launcher, IMS, The Opus Way, Sri Ram Coaching, Clat Possible, TYC etc. Moreover, for your help Careers 360 is giving you mock-series and sample papers free of cost, just download them using the link given below: https://law.careers360.com/articles/clat-mock-test
