In how many regional languages is JEE Main Computer Based Examination conducted?

JEE Main is administered in 13 languages: English, Hindi, Assamese, Bengali, Gujarati, Kannada, Malayalam, Marathi, Odia, Punjabi, Tamil, Telugu, and Urdu, matching the language options available across all major central and state educational boards.

What is the 75% Class 12 board marks eligibility criteria for admission into NITs and IIITs?

Candidates must secure at least 75% aggregate marks in Class 12 (65% for SC/ST) OR be in the top 20 percentile of their respective State or Central Board's Class 12 examination. Meeting this board threshold is compulsory to confirm seat allocation in NITs, IIITs, and GFTIs through JoSAA.

How is the percentile calculated in JEE Main across different shifts?

Because JEE Main is conducted across multiple shifts with varying question papers, raw marks are converted into NTA Percentile Scores using normalization based on candidate relative performance in that specific shift.

Is there negative marking in Section B (Numerical Value Questions)?

Yes. Since 2022, NTA introduced negative marking in Section B as well. Incorrect answers in both Section A (MCQs) and Section B (Numerical) incur a -1 mark penalty (+4 for correct).

What is the 75% eligibility criteria in Class 12?

To secure admission into NITs, IIITs, and GFTIs (and IITs via JEE Advanced), candidates must have secured at least 75% aggregate marks in Class 12 (65% for SC/ST/PwD) OR be in the top 20 percentile of their respective board exam.

Toppers' Golden Rules

•Time Management is Everything: Never get stuck on a difficult 10-minute math problem. Solve all easy questions in Chemistry and Physics first to build a solid 140+ foundation.
•Chemistry is the Rank Booster: Chemistry can be completed in 35-40 minutes and yields 75+ marks easily.
•Both Sessions Count: Appear for both Session 1 (January) and Session 2 (April). NTA takes the best of the two percentiles for your final All-India Rank.
•75% Board Eligibility Rule: Ensure you secure at least 75% aggregate in your Class 12 board exams (65% for SC/ST), otherwise JoSAA will cancel your NIT/IIIT admission regardless of your 99.9 percentile.

Fatal Mistakes to Avoid

•Neglecting NCERT Chemistry and reading complex foreign author books instead.
•Attempting questions in Section B in a hurry without checking the easiest 5 options.
•Letting board exams slide and scoring under 75% in Class 12.
