Joint Entrance Examination (JEE) is an engineering entrance examination conducted for admission to various engineering colleges in India. It is constituted by two different examinations - JEE Main and the JEE Advanced. The Joint Seat Allocation Authority (JoSAA) conducts the joint admission process for a total of 23 Indian Institute of Technology campuses, 32 National Institute of Technology campuses, 18 Indian Institute of Information Technology campuses and 19 other Government Funded Technical Institutes (GFTIs) based on the rank obtained by a student in JEE Mains and JEE Advanced. There are some institutes like Indian Institutes of Science Education and Research (IISERs), Rajiv Gandhi Institute of Petroleum Technology (RGIPT), and Indian Institute of Science (IISc) use the score obtained in JEE Advanced as the basis for admission. These institutes do not participate in the post examination counselling session. Any student who takes admission to IITs cannot appear for the JEE-Advanced exam in the next year, but the same is not the case with IISc, IISER, RGIPT and other institutes as these institutes only use JEE Advanced score for admission.
