What is IIT JAM?

Joint Admission Test for MSc (JAM) is an all-India level online entrance exam conducted by the Indian Institute of Technology (IITs) every year on a rotational basis on behalf of the Ministry of Human Resources Development (MHRD), Government of India. Candidates are informed that the biometric system of identity verification (fingerprint) will be used for JAM exam as well as admission. IIT JAM is conducted to provide admission to candidates in MSc and other postgraduate courses offered at IITs and integrated PhD courses offered by the Indian Institute of Science (IISc), Bangalore.
