Earlier, the IITs conducted their exclusive Joint Entrance Examination for admission to their various engineering courses. However, since 2013, CBSE is conducting a common entrance, clubbing both AIEEE and IIT-JEE.
Joint Entrance Examination (JEE) is conducted in two parts – JEE-Main and JEE- Advanced.
JEE-Main qualifies students to seek admission to 23 IITs, Indian School of Mines (Dhanbad), 18 IIITs (Indian Institutes of Information Technology), 32 NITs (National Institute of Technology), 19 Government Funded Technical Institutes (GFTIs) followed by other state-level and private engineering colleges.
As the IITs are the most prestigious institutes in the country, only the top 2,20,000 rankers of JEE-Main is eligible to appear in the JEE-Advanced. Needless to say, JEE-Advanced is tougher than JEE-Main, selecting students for the 23-IITs spread across the country and the Indian School of Mines, Dhanbad.
JEE-Main has two papers. You may opt for either or both of them. Both papers contain multiple choice questions.
Paper 1: Held for admission in B.E./B.Tech (online and offline). One objective type question paper will have questions from Physics, Chemistry and Mathematics. Duration of the test is three hours and you can appear either in the computer-based test or pen and paper test.
Paper 2: For admission in B.Arch and B.Planning (offline only). It has three parts: Mathematics, Aptitude Test and Drawing test, following the past AIEEE pattern. It is also of three-hour duration with only the first two parts objective.
There is negative marking for incorrect answers. 4 marks are awarded for correct answers and 1 mark is deducted for incorrect answers.
Note: From 2013 to 2016, the marks obtained in the class XII school board examination used to be accorded a 40% weightage in deciding the JEE Mains all India ranks but from 2017 onward, this has been discontinued.
However, to qualify for admissions to NITs/IIITs/GFTIs, you should have secured at least 75% marks in class 12th exam or be in the top 20 percentile in the class 12th exam.
Pattern of Advanced is quite similar to Main, except for its level of difficulty. Advanced has two parts. Duration of each part is three hours with separate sections on Physics, Chemistry and Mathematics. Question paper is objective, designed to test the comprehension, reasoning and analytical ability of candidates.
There will also be one-fourth negative marking for each incorrect answer.
This is an offline pen and paper test where answers are to be marked on Optical Response Sheet. Students who obtain All India Ranks (AIRs) and wish to study Architecture or Design need to appear for an Architecture Aptitude Test (AAT) and qualify.
