Hello Aftab,

It would be difficult to tell you the rank as per your score as It 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.

Indian Institute of Technology, Kharagpur, the conducting body of JAM, will release IIT JAM 2019 result on March 20, 2019 with the rank secured by the candidates along with the qualifying status, I would suggest you to wait.

You can check the further detail with the given below link.
