Quick Facts
2027 Dates
Eligibility
- Passed Class 12 in 2025 or 2026, or appearing in 2027.
- No age limit. NTA does not ask for a minimum percentage to appear.
- For NIT, IIIT and GFTI admission, you need 75% in Class 12 (65% for SC/ST), or a place in the top 20 percentile of your board.
- Physics and Maths are compulsory in Class 12, plus one of Chemistry, Biology, Biotechnology or a technical vocational subject.
Exam Pattern (Paper 1)
- Duration: 3 hours.
- Marking: +4 / −1 for both MCQs and numericals. All 75 questions are compulsory (the old optional numerical choice was removed in 2025).
- Results come as NTA percentile scores, normalised across shifts.

When to Start Preparing
Strategy tips
- NCERT is non-negotiable for Chemistry, especially Inorganic.
- Take 2 full mocks a week from November onward, and analyse each one for at least 2 hours.
- Keep a "mistake notebook" and a formula sheet for each subject.
- Use Session 1 as a real-exam rehearsal and Session 2 to improve your score.
Recommended Books
- NCERT Class 11 & 12 (all three subjects)
- Physics: H.C. Verma, D.C. Pandey (Arihant)
- Chemistry: N. Awasthi (Physical), O.P. Tandon, M.S. Chouhan (Organic practice)
- Maths: R.D. Sharma (basics), Cengage (G. Tewani), Arihant Skills in Maths
- Previous years' JEE Main chapter-wise solved papers
After the Exam
- Top 2.5 lakh candidates (by category) qualify for JEE Advanced.
- JoSAA counselling covers IITs, NITs, IIITs and GFTIs. CSAB special rounds follow.
- Many states, such as Maharashtra (All-India quota), Haryana, Odisha and Delhi, also accept JEE Main scores.
