ABOUT JEE MAINS AND ADVANCE

Joint Entrance Examination (JEE) is an all India common entrance examination which is conducted for admission in various engineering courses. In 2012, CBSE (Central Board of Secondary Education) has announced this common examination in place of AIEEE and IIT-JEE. JEE (Joint Entrance Examination) is being conducted into two parts, JEE-Main and JEE-Advanced. JEE-Advanced is for admission in Indian Institutes of Technology (IITs), and Indian School of Mines Dhanbad (now getting converted into IIT) and JEE-Main exam is to admission in IIITs (Indian Institutes of Information Technology), National Institutes of Technology, CFTIs (Central Funded Technical Institute) and IIEST Shibpur, for admission to its dual degree programme.
As IIT's and ISM are the premier engineering and science colleges in India, the candidates have to clear the second level of exam JEE-Advanced for securing admission in them. Only top candidates of JEE-Mains are eligible to appear for JEE-Advanced exam. The candidates who clear JEE-Advanced exam have the opportunity to join either of the IIT's or ISM. The candidates who clear JEE-Mains but are not eligible for JEE-Advanced can seek admission in other engineering colleges such as Indian Institute of Information Technology, National Institute of Technology, and other government and private engineering colleges.
There are some colleges like IISER's, RGIPT and others which uses score of JEE Advanced for admission. These are not participating institutes of Central IIT JEE Advanced counselling of which all IITs and ISM is a member. Any student who takes admission in IIT's and ISM Dhanbad (now getting converted into IIT) cannot appear for JEE-Advanced exam next year, but the same is not the case with IISER, RGIPT and other institutes as these institutes only use JEE Advanced score and they have no connection with IIT central counselling.
In September 2013, the IIT Council approved the decision of the Joint Admission Board to continue with the two-phase JEE pattern ("Main" followed by "Advanced") for IITs in 2014. The 2014 Joint Entrance Examination Results (JEE-Mains 2014) was announced on 3 May 2014. The JEE-Mains for 2015 was held on April 4, 2015.
