Hello sir, I’m preparing for JAM exam. I want some previous year question paper for Jam exam. Please provide me question paper for Jam Exam?

[shikha]

JAM (Joint Admission Test) is scheduled to be held on 12th February, 2017.
Cracking the Joint Admission Exam in the very first attempt is the main goal of many B.Sc. Graduates who want to pursue M.Sc from premier institution like IITs and IISc.

JAM Application Form is available for M.Sc as per the schedule. After submission of IIT JAM Application Form, candidate is not required to send any documents.

The organizing body for Joint Admission Test for M.Sc is IIT.

Here I’m attaching PDF of previous year question paper for Jam exam:
