JEE Main 2027 at a glance#
JEE (Main) is conducted by the National Testing Agency (NTA). It decides admission to NITs, IIITs and other centrally funded institutes through JoSAA, and it is also the qualifying exam for JEE (Advanced), the gateway to the IITs. In JoSAA 2026, the participating institutes included 31 NITs and 26 IIITs. In 2026, about 15.38 lakh unique candidates appeared for Paper 1 across the two sessions, according to NTA.
As of 7 October 2026, NTA has tentatively scheduled Session 1 of JEE (Main) 2027 for 22 to 24 and 28 to 30 January 2027 in its examination calendar. The 2027 information bulletin, registration dates and Session 2 dates are not out yet. Our JEE Main 2027 guide tracks dates, eligibility and the 75% criteria, and the JEE Main exam page has the exam overview.
Understand the exam pattern#
This is the Paper 1 (B.E./B.Tech) pattern from the JEE (Main) 2026 information bulletin. Check the 2027 bulletin for any change.
| Parameter | Details |
|---|---|
| Conducting body | National Testing Agency (NTA) |
| Official website | jeemain.nta.nic.in |
| Mode | Computer-based test |
| Duration | 3 hours |
| Questions | 75: in each of Physics, Chemistry and Maths, 20 MCQs (Section A) and 5 numerical value questions (Section B) |
| Total marks | 300 |
| Marking | +4 correct, −1 wrong, 0 unanswered, in both sections |
| Sessions | Two sessions a year; if you write both, the better NTA score counts |
The key change many older guides miss: numerical value questions also carry negative marking, so guessing there costs marks too.
Your result is an NTA score (percentile), not raw marks. To understand how marks turn into percentile and rank, read JEE Main marks vs percentile.
Know your priority chapters#
NTA does not publish chapter-wise weightage, but past papers show that some units appear in almost every shift. In brief:
- Physics: mechanics (especially Rotational Motion), Electrostatics, Current Electricity, Magnetic Effects, Optics and Modern Physics.
- Chemistry: Chemical Bonding, Coordination Compounds, p-, d- and f-block elements, Equilibrium, Thermodynamics, Electrochemistry, General Organic Chemistry and oxygen-containing compounds.
- Maths: Integral Calculus, Limits and Differentiability, Coordinate Geometry, Vectors and 3D Geometry, Matrices and Determinants, Sequence and Series, Statistics and Probability.
The full tier list for every syllabus unit is in our JEE Main chapter wise weightage guide.
Subject-wise strategy#
Physics
Physics rewards understanding over memory. For each chapter, learn where every formula comes from, solve the NCERT examples, then move to mixed problems. Draw a diagram for every mechanics and optics question, write units at each step, and check limiting cases (what happens if a mass or angle becomes zero). Most lost marks in Physics come from sign errors and unit slips, so track them in your error notebook.
Chemistry
Treat the three parts differently. Physical Chemistry is numerical: practise problems daily, like Maths. Inorganic Chemistry is close to NCERT: read the text several times and make short lists of exceptions, colours and trends. Organic Chemistry is about mechanisms: learn why a reaction happens, then practise conversions. Chemistry questions are often quicker to answer, which can save time for Maths.
Mathematics
Maths needs daily practice to keep speed. Learn the standard methods for each unit, then solve mixed sets so that you can recognise which method a question needs. Calculus and Coordinate Geometry take the most time to master, so start them early. In mocks, skip any question that is taking too long and come back to it in the next round.
Common mistakes to avoid#
- Collecting too many books. One reference per subject, finished properly, is enough.
- Leaving PYQs to the end. Solve them chapter by chapter as you go.
- Taking mocks without analysis. The learning happens in the review, not the test.
- Ignoring negative marking in Section B. Wrong numerical answers also cost a mark.
- Skipping revision. Plan a revision slot every week from the start, not only in the last month.
The 6-month JEE Main study plan#
Use this if you have about six months and have studied at least part of the Class 11 syllabus at school.
Months 1 and 2: concepts and NCERT
- Read Class 11 and 12 NCERT chapters for the units you are studying, including examples and tables.
- Solve NCERT exercises before moving to any reference book.
- Make a one-page formula and key-facts sheet for every chapter.
- Start high-priority chapters first in each subject.
Months 3 and 4: problem solving
- Move to one reference book per subject (see the books section below).
- Solve a fixed number of problems every day in each subject, mixing easy and hard.
- Add previous year questions for each chapter as soon as you finish it.
- Keep an error notebook: every wrong question, why you got it wrong and the correct method.
Months 5 and 6: mocks and revision
- Take a full-length 3-hour mock test once or twice a week at first, then more often in the final month.
- Analyse every mock: accuracy, time per subject and marks lost to negative marking.
- Solve recent full shift papers from jeemain.nta.nic.in under timed conditions.
- Revise formula sheets and your error notebook daily.
90-day plan for JEE Main#
For students with about three months, which is roughly the time left before Session 1 in January 2027 from early October.
| Weeks | Focus |
|---|---|
| 1 to 4 | High-priority chapters in all three subjects: NCERT, then chapter PYQs. One subject block per day, rotating. |
| 5 to 8 | Medium-priority chapters, same method. Start one full mock test every week. |
| 9 to 10 | Lower-priority chapters and weak spots from your error notebook. Two mocks a week. |
| 11 to 12 | Full revision of formula sheets; recent full shift papers under timed conditions; no new books. |
| 13 | Light revision, sleep schedule matched to your exam shift, admit card and documents ready. |
60-day plan#
With two months, cut breadth, not depth.
- Weeks 1 to 3: high-priority chapters only. For each: quick NCERT revision, key formulas, then PYQs.
- Weeks 4 to 5: medium-priority chapters you have studied before. Skip starting long, unfamiliar units from scratch.
- Weeks 6 to 7: a full mock every two to three days, with analysis the next day. Fix the top three weak spots each week.
- Week 8: revision from your own notes and error notebook; recent shift papers only.
30-day plan#
One month is enough to raise your score if you focus on revision and accuracy rather than new topics.
- Days 1 to 10: revise high-priority chapters from your notes; solve their PYQs.
- Days 11 to 20: a full mock every alternate day; on the other days, revise the chapters where you lost the most marks.
- Days 21 to 27: recent full shift papers, timed; formula sheets daily.
- Days 28 to 30: light revision only, no new material, and rest.
In the last month, accuracy matters more than attempts. With −1 for every wrong answer, four wrong answers cancel one correct one.
A daily JEE Main timetable#
A sample day for a student who also attends school. Adjust it to your own routine.
| Time | Activity |
|---|---|
| Early morning (1.5 hours) | Revise yesterday's topics and formula sheets |
| School or coaching hours | Classes |
| Evening block 1 (2 hours) | New concepts in one subject |
| Evening block 2 (1.5 hours) | Problems and PYQs in a second subject |
| Night (1 hour) | Short practice in the third subject, update error notebook |
| Weekly | One full mock test and its analysis |
Rotate the subjects so that each one gets new study and practice time every two days. Sleep at a regular time; tired study gives poor retention.
Best books for JEE Main: in brief#
Start with the NCERT Class 11 and 12 textbooks and add just one reference book per subject, such as H.C. Verma for Physics, O.P. Tandon or N. Avasthi for Physical Chemistry with NCERT for Inorganic and Organic, and R.D. Sharma or Cengage for Maths. Our full list with authors, publishers and which books suit JEE Main or Advanced is on the best books for JEE page.
Previous year questions#
Past papers are the closest thing to the real exam. NTA publishes recent question papers and final answer keys on jeemain.nta.nic.in. Our JEE Main PYQ chapterwise guide explains how many years to solve and how to move from chapter-wise practice to full papers.
JEE Main mock test strategy and exam day#
- Simulate the real exam. Three hours, no phone, at the same time of day as your shift.
- Use a three-round approach. First round: answer every question you can solve quickly. Second round: questions that need longer working. Third round: review marked questions and check calculations.
- Do not guess blindly. Every wrong answer costs 1 mark, in both MCQ and numerical sections. Answer only when you can eliminate options or have a worked value.
- Watch your time per subject. Note in mocks where you overspend, and set a rough time budget.
- Analyse more than you test. A mock without analysis is wasted. Record wrong answers in your error notebook and revise those chapters before the next mock.
