JEE Main at a glance
The Joint Entrance Examination (JEE) Main is the national entrance test for admission to undergraduate engineering and architecture programmes at the NITs, IIITs, other centrally funded technical institutions and many state and private colleges, and it is also the qualifying test for JEE (Advanced), the entrance exam for the IITs. It is conducted by the National Testing Agency (NTA) in computer-based mode, and in 2026 it was held in two sessions, in January and April. Paper 1 is for B.E. and B.Tech; Papers 2A and 2B are for B.Arch and B.Planning.
| Detail | JEE Main 2026, Paper 1 (B.E./B.Tech) |
|---|---|
| Conducted by | National Testing Agency (NTA) |
| Mode | Computer-based test |
| Sessions in 2026 | Session 1 in January and Session 2 in April |
| Subjects | Mathematics, Physics, Chemistry |
| Questions | 75: 25 per subject, made up of 20 multiple-choice questions and 5 numerical-value questions, all compulsory |
| Marks | 300: 100 per subject |
| Marking | +4 for a correct answer, −1 for a wrong answer, 0 for unattempted; the negative mark applies to numerical-value questions as well |
| Duration | 3 hours |
The pattern above is as reported from the NTA's 2026 information bulletin by several education news sources. The most important change in recent years is that the optional-question format, under which candidates attempted five of ten numerical questions in each subject, has been discontinued, so all five numerical questions in each subject are now compulsory and carry negative marking. Check the NTA information bulletin on the official JEE Main website for the details for your session.
Who takes JEE Main, and what the score is used for
JEE Main is taken by lakhs of Class 12 students and repeaters each year. The score decides admission to engineering programmes through the Joint Seat Allocation Authority (JoSAA) counselling process, which uses JEE Main ranks for NITs, IIITs and other participating institutions, and the top performers qualify to appear in JEE (Advanced). Where a candidate is allowed more than one session, the best of the scores is generally used. Eligibility conditions, including the number of attempts allowed, the qualifying examination and the minimum marks, are set in the NTA bulletin and by the counselling authorities, so please read the current documents rather than relying on a summary.
The three subjects
Mathematics
Mathematics is the longest section in practice, because many questions need multi-step calculation. It rewards fluency in algebra, calculus and coordinate geometry. See JEE Main Mathematics mock tests.
Physics
Physics mixes direct formula questions with a few multi-concept problems. Numerical-value questions put a premium on accuracy because there are no options to check against. See JEE Main Physics mock tests.
Chemistry
Chemistry is often the section that a prepared candidate finishes fastest, because many questions test recall of facts, trends and reactions. See JEE Main Chemistry mock tests.
Syllabus areas
The NTA publishes the syllabus for each session, and some topics have been rationalised in recent years. The summary below shows the main areas and should be checked against the current document.
| Subject | Main areas |
|---|---|
| Mathematics | Sets, relations and functions; complex numbers; quadratic equations; matrices and determinants; permutations and combinations; binomial theorem; sequences and series; limits, continuity and differentiability; integral calculus; differential equations; coordinate geometry; three-dimensional geometry and vectors; trigonometry; statistics and probability |
| Physics | Units and measurements; kinematics; laws of motion; work, energy and power; rotational motion; gravitation; properties of solids and fluids; thermodynamics; oscillations and waves; electrostatics; current electricity; magnetism and electromagnetic induction; optics; dual nature of matter; atoms and nuclei; electronic devices |
| Chemistry | Physical: mole concept, atomic structure, thermodynamics, equilibrium, kinetics, electrochemistry. Inorganic: periodic table, bonding, s-, p-, d- and f-block elements, coordination compounds. Organic: general organic chemistry, hydrocarbons, functional groups, biomolecules |
Why mock tests matter for JEE Main
With 75 compulsory questions in 180 minutes, JEE Main gives you an average of two and a half minutes per question, but the distribution is uneven: a direct Chemistry question takes 40 seconds, a Mathematics calculus problem can take four minutes. Mock tests teach three things that textbooks cannot:
- Allocation. Learning to spend less on Chemistry and more on Mathematics, and where to stop on a question that is eating your time.
- Handling numerical-value questions. There are no options to back-solve from and a wrong answer now costs a mark, so each needs a clean method and a check.
- Stamina and screen skills. Three hours of computer-based work, with an on-screen keypad for numerical answers, is a skill in itself.
Types of mock tests and when to use each
| Type | Typical length | Best used for |
|---|---|---|
| Chapter tests | 15-25 questions | Checking a chapter after studying it; repairing weak chapters |
| Subject tests | 25 questions in about 60-75 minutes | Pace and accuracy in one subject; practising the 20 + 5 split |
| Part-syllabus tests | 75 questions, selected chapters | Rehearsal as syllabus coverage grows |
| Full-syllabus tests | 75 questions, 3 hours | Final rehearsal: sequencing, stamina and negative-marking policy |
| Previous-year-style papers | Full paper | Calibrating difficulty and the style of recent questions |
The stage-by-stage plan is in the JEE Main mock test strategy.
Free and paid JEE Main mocks
Free tests are a good way to find your baseline and to sample an institute's style. Paid series usually give more full-length papers, graded difficulty, detailed solutions and analytics. The lists below show what is currently published on TestMint, and the free JEE Main mock tests page explains how to get a baseline from a free attempt. For what to look for, see what makes a good mock test.
Test-taking strategy for the 75 questions
A first pass should collect the marks that are certain: in each subject, go through the 25 questions, answer those where you can see the method, and mark the rest. Most candidates find Chemistry the quickest, Physics moderate and Mathematics the slowest, so a common sequence is Chemistry, then Physics, then Mathematics, with about 35 to 40 minutes for Chemistry, about 55 minutes for Physics and about 70 for Mathematics, leaving around 15 to 20 minutes to return to marked questions. The right sequence is individual: test alternatives across mocks and keep the one that gives the highest net score.
Numerical-value questions deserve their own routine. Before you type an answer, check units, check that it is an integer (if the question asks for a rounded value, see how the rounding is specified) and re-read what was asked. Because there is a penalty, an unchecked numerical answer is a risk, so treat these five questions per subject as questions you answer only when your method is complete.
Negative marking: how to think about it
With +4 and −1, the break-even accuracy for a guess is 20%: a wrong answer costs one-fourth of what a right one earns. For an MCQ with four options, a blind guess has a positive expected value of +0.25 marks, and elimination of an option raises it to +0.67. That is true for the MCQs. For numerical-value questions, a blind guess has essentially no chance of being right, so the expected value is close to −1: leave them unless you have a computed answer. Our guide to negative marking and the worked example in accuracy versus attempts set out the arithmetic.
Analysing a JEE Main mock
| Cause | What it looks like | What to do next |
|---|---|---|
| Concept gap | You could not start the problem | Study the idea; solve 10-15 problems on it within a week |
| Calculation error | Correct method, wrong number (common in numerical-value questions) | Write steps; estimate; slow down on the last step |
| Reading error | Answered a different question or missed a condition | Underline the ask and the conditions |
| Selection error | Spent six minutes on a question that was not worth it | Set a time ceiling; mark and return |
| Guess error | Marked an MCQ with no elimination or guessed a numerical answer | Define a policy from your record |
| Pressure error | Rushed the last 20 minutes and lost easy marks | Rehearse the time plan; keep a ten-minute buffer |
Redo the questions you skipped without a clock, to see whether your skips were sensible. See how to review incorrect questions and how to build an error log.
Common mistakes in JEE Main preparation
- Treating the numerical section as optional. It is compulsory now, and it carries a penalty.
- Taking many full mocks and reviewing few. A mock without a review gives a score, not an improvement.
- Starting every full mock with the subject you like. Experiment with sequences.
- Neglecting Chemistry. It is the quickest section, and every minute saved there goes to Mathematics.
- Using mocks from an older pattern without adjusting. Check the structure of any test you use.
A preparation timeline using mocks
Class 11 and 12 (two-year plan): chapter tests after each chapter. Six to four months out: subject tests every week and part-syllabus tests every month. Four to two months: a full-syllabus test each week with a full day of review. The last two months: two tests a week at most, concentrating on your error log and time plan. The last week: a final test four or five days before, light revision and rest. Because JEE Main has two sessions, plan your first session as a serious attempt and use the weeks between the sessions to repair what the result showed. For shorter timelines see the 30-day plan and the last-week plan.
