Joint Entrance Examination – Advanced (JEE-Advanced), formerly the Indian Institutes of Technology-Joint Entrance Examination (IIT-JEE), is an academic examination held annually in India. It is organized by one of the seven "old" IITs (IIT Roorkee, IIT Kharagpur, IIT Delhi, IIT Kanpur, IIT Bombay, IIT Madras, and IIT Guwahati)^[3] under the guidance of the Joint Admission Board (JAB). It is the sole prerequisite for admission to the Indian Institutes of Technology. Other universities—such as the Marine Engineering and Research Institute, Indian Institute of Petroleum and Energy (IIPE), the Rajiv Gandhi Institute of Petroleum Technology, the Indian Institute of Space Technology (IIST), the Indian Institute of Science Education and Research (IISERs), and the Indian Institute of Science (IISc) — use the score obtained on the JEE-Advanced exam as the basis for admission. The JEE-Advanced score is also used as a possible basis for admission by Indian applicants to non-Indian universities such as the University of Cambridge and National University of Singapore.^[4][5] The examination is organized each year by one of the IITs, on a round-robin rotation pattern.
