IIT JAM Physics Exam
Joint Admission test for Masters (JAM) has been established as a benchmark for undergraduate level science education in the country from last two decades. The objective of JAM is to provide admissions to postgraduate Degree Programmes and to consolidate Science as a career option for students across the country. These programmes offer high-quality education in their respective disciplines, comparable to the best in the world. The curricula for these programmes are designed to provide the students with opportunities to develop academic talent leading to challenging and rewarding professional life. The interdisciplinary content of the curricula enable the students with the ability to utilize scientific knowledge for practical applications. These programmes are open to all eligible students irrespective of their nationality. The medium of instruction is English for all the programmes.
