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, that are objective pattern. JEE Advanced is regarded internationally as one of the most challenging undergraduate admission tests.
In 2012, the government-run Central Board of Secondary Education (CBSE) that earlier conducted the AIEEE, announced the JEE that replaced the AIEEE and IIT-JEE. The JEE-Main, which replaces AIEEE, is for admission to the National Institutes of Technology (NITs), Indian Institutes of Information Technology (IIITs), and some other colleges designated as "centrally funded technical institutes" (CFTIs). The JEE-Advanced, which replaces IIT-JEE, is for admission to the Indian Institutes of Technology (IITs). Only the students selected in JEE Main are eligible for appearing in JEE Advanced. There are some institutes like the Indian Institutes of Science Education and Research (IISERs), Rajiv Gandhi Institute of Petroleum Technology, and the Indian Institute of Science.
