Hello Mayank,

IIT JAM is the entrance Exam for the admission to M.Sc, Joint M.Sc-Ph.D, M.Sc Ph.D dual programme, integrated PhD, M.Sc-M.Tech and M.Sc-M.S (Research) in as many as 20 IITs and IISc Bangalore.

It would be difficult to tell you the exactly about the admission chances in IITs as cutoff varies every year depending on the various factors such as difficulty level of the exam, Number of candidates appeared for the exam, Performance of the candidates etc.

However you can check the previous year cutoff to take an Idea about the admission possibilities.
