JEE Mains 2027 Session 1 is expected in January 2027 — that is approximately 7 months away. For most aspirants reading this in June or July 2026, this is the best possible time to start a structured, pressure-free preparation cycle.
This guide gives you everything: exam pattern, syllabus, month-wise plan, best books, and the most important chapters to prioritise.
JEE Mains 2027 — Key Facts
The National Testing Agency will release the official notification for JEE Mains 2027 in October 2026. JEE Main 2027 will have two sessions: Session 1 in the last week of January 2027, and Session 2 in the first week of April 2027.
| Detail | Expected | | :--- | :--- | | Session 1 | Last week of January 2027 | | Session 2 | First week of April 2027 | | Mode | CBT (Computer Based Test) | | Notification Release | October 2026 | | Registration Opens | October–November 2026 | | Total Questions | 75 (25 each: Physics, Chemistry, Maths) | | Total Marks | 300 | | Marking Scheme | +4 correct, -1 wrong |
Two sessions means two chances. Most serious aspirants appear in both. Your best score between the two sessions counts for admission to NITs, IIITs, and GFTIs. Clearing JEE Mains also makes you eligible for JEE Advanced — the gateway to all 23 IITs.

JEE Mains 2027 Exam Pattern
JEE Main Paper 1 has 75 questions in total. Each subject has 25 questions — 20 MCQs and 5 Numerical Value Questions. Section B with Numerical Value Questions is compulsory in JEE Main 2027. The earlier option of choosing 5 out of 10 questions has been removed.
| Section | Questions | Marks | Negative Marking | | :--- | :--- | :--- | :--- | | Physics MCQ | 20 | 80 | Yes (-1) | | Physics Numerical | 5 | 20 | Yes (-1) | | Chemistry MCQ | 20 | 80 | Yes (-1) | | Chemistry Numerical | 5 | 20 | Yes (-1) | | Maths MCQ | 20 | 80 | Yes (-1) | | Maths Numerical | 5 | 20 | Yes (-1) | | Total | 75 | 300 | |
This means all 5 Numerical Value Questions per subject are compulsory and carry negative marking. Accuracy matters as much as speed — one wrong numerical costs you 5 marks (4 lost + 1 penalty).
JEE Mains 2027 High Priority Chapters

- Take 3 full mock tests this month
#### Phase 5 — Final Preparation (January 2027)
- Formula sheet revision only — no new topics

- Session 1 exam: last week of January 2027
Best Books for JEE Mains 2027
| Subject | Primary | Reference | | :--- | :--- | :--- | | Physics | NCERT + H.C. Verma Vol 1 and 2 | D.C. Pandey for practice | | Chemistry | NCERT (mandatory for all sections) | O.P. Tandon Organic, NCERT Inorganic | | Mathematics | NCERT + R.D. Sharma Objective | Cengage or Arihant for practice |
NCERT is non-negotiable. At least 60–70% of Chemistry and a significant portion of Physics in JEE Mains are directly rooted in NCERT. Do not skip NCERT even if you are using coaching material.
JEE vs NEET — Preparing for Both
If you are preparing for both JEE Mains and NEET simultaneously, here is how the two exams compare:
| Factor | NEET | JEE Mains | | :--- | :--- | :--- | | Biology | 360 marks | Not required | | Mathematics | Not required | 100 marks | | Physics depth | Moderate | High — more numerical | | Chemistry | NCERT-heavy | NCERT + application | | Total marks | 720 | 300 | | Mode | CBT (from 2027) | CBT |
Students taking both exams should study Physics and Chemistry together and add Biology (for NEET) or Mathematics (for JEE) as separate subjects daily.
5 Mistakes JEE Aspirants Make Starting in July
- 1. Skipping NCERT Chemistry in JEE Mains is 60–70% NCERT-based, especially Inorganic. Skipping NCERT costs 20–30 marks directly.
2. Ignoring Numerical Value Questions NVQs are now compulsory in all three subjects and carry negative marking. Most students only practice MCQs and lose marks here unnecessarily.
3. Treating Maths as a theory subject JEE Maths is entirely problem-solving from day one. Reading concepts without solving problems every day is wasted preparation time.
4. Underestimating Session 1 Both sessions count independently. Session 1 in January often has slightly easier papers because fewer students are fully prepared. Take it seriously.
5. Not using CBT practice JEE is computer-based. Practising only on paper means you are unfamiliar with the interface, the on-screen calculator, and the navigation on exam day.

Frequently Asked Questions
Q: Is 7 months enough to prepare for JEE Mains 2027 Session 1? Yes, if you start in July 2026 with a structured plan. 7 months is a full preparation cycle for JEE Mains. Many students qualify JEE Mains with 85+ percentile after 6–7 months of focused preparation.
Q: Should I appear in both JEE Mains sessions? Yes — always. Your best score between Session 1 and Session 2 counts. Even if Session 1 goes well, appearing in Session 2 gives you a safety net and a chance to improve.
Q: What percentile do I need to qualify for JEE Advanced? Approximately top 2,50,000 ranks from JEE Mains qualify for JEE Advanced. For General category, this typically requires 85–90+ percentile in JEE Mains.
Q: How many mock tests should I take for JEE Mains? Aim for at least 20–25 full-length mock tests before Session 1. Start with 1 per week in July–October, then increase to 3 per week in November–January.
Q: Which is harder — JEE Mains or NEET? They test different things. JEE Mains requires deeper problem-solving in Physics and Maths. NEET requires broader coverage of Biology from NCERT. Neither is universally harder — it depends on your strengths.
Final Word
Seven months is a complete preparation cycle for JEE Mains. The aspirants who start in July with a diagnostic test, build their foundation methodically, and enter mock-test mode by November are the ones who walk into January 2027 feeling ready and confident.
Do not wait for the perfect plan. Start with one free diagnostic test today — it will tell you your current level and which chapters to fix first.
