What is JEE Mains? & Why JEE Mains ?
JEE Mains(Joint Entrance Examination) is an Engineering Entrance examination for admission into Undergraduate Engineering Programs at NITs, IIITs, Other Centrally Funded Technical Institutions, Institutions funded by participating State Governments and other Institutions. The Paper-1 (B. E./B. Tech.) of JEE (Main) will also be considered for JEE (Advanced), which the candidate should appear for getting admitted into the undergraduate programmes offered by the IITs.
- The NTA (National Testing Agency) will conduct the JEE Mains(Joint Entrance Examination)-2019
Between 06.01.2019 to 20.01.2019
- From 1st Week of SEPTEMBER-2018, Online registration for JEE Mains-2019 will be open. Here you can find how to apply for JEE mains-2019, Examination Centres, Syllabus, Important Dates, Seat Matrix and courses availability
Important Points in JEE Mains 2019:
- The JEE (Main)-2019 will be conducted twice before admissions from this academic session.
The first attempt of JEE (Main) - 2019 will be held in January, 2019 whereas the second attempt will be held in April, 2019. The test will be held on different shifts/dates in both the attempts. The NTA will release the application form of JEE (Main)-2019 for the first attempt in September, 2018 and for the second attempt in February, 2019.
The students will have the following benefits of the new pattern:
- This will give one more opportunity to the student to improve their scores in examination if they fail to give their best in first attempt without wasting their whole academic year.
- In first attempt, the students will get a first-hand experience of taking an examination and to know their mistakes which they can improve while attempting for the second time.
- The student's best of the two scores will be considered for preparation of Merit List/ Ranking.
- There shall be No Weightage For The 12th Class marks in calculating the ranks in the JEE (Main) examination
