Hello Ayush,

IIT JAM is an entrance exam conducted for the admission to the postgraduate programmes offered by IIT’s and IISc. Bangalore.

It would be difficult to tell you about the admission chances in IITs as per your score as cutoff varies every year depending on the various factors such as No. of candidates appeared for the exam, Difficulty level of the exam, Performance of the candidates etc. However you can prefer the previous year cutoff rank of each IIT to take an Idea about the admission possibility.
