JAM is an abbreviated form of (Joint Admission Test) for M.Sc. (JAM) conducted by the Indian Institute of Technology (IITs) for admission in Ph.D. Degree programs at IISc, Bangalore and M.Sc. (Two Years), Joint M. Sc. -Ph.D. Dual Degree, Joint M.Sc. –Ph.D., M. Sc. -M. tech, M.Sc. – M.S. (Research) /Ph.D. Dual Degree and other Post-Bachelor’s Degree Programs at IITs. The main objective of this exam is to consolidate Science as a career option for bright students across the country. The academic environment, interdisciplinary interaction and research infrastructure which are given to the student at these top Institutes like IISC Bangalore and IITs motivate the scholars to pursue their career not only in research and development of basic science but also in the interdisciplinary areas of Science and Technology.
The entrance exam is open to all Indians without any age limit. The applicant should have scored at least 55% marks (for general categories / OBC) and 50% marks for SC, ST and PD category candidates in the bachelor degree. The candidates who have appeared or are waiting for the final result are also eligible to participate in the entrance exam. The candidates who have cleared BSc through distance education or correspondence course have to appear for the additional interview for admission into M.SC. physics or M.SC. mathematics.
Good quality education is a useful resource for your bright future. The institutions like IITs and IISc provide you world quality infrastructure and exposure to globally accepted education. These institutions get more than 50% of the government budget for higher education. One should not miss the opportunity if he/she is wanting to pursue higher education.
