The syllabus of JEE Mains 2027 acts as the base for those who are looking forward to pursuing their career through engineering undergraduate programs. In addition to the syllabus, knowledge about JEE Main chapter wise weightage will help the candidates in organizing their preparation.
The following section includes JEE Main 2027 syllabus for Physics, Chemistry and Mathematics along with the chapter wise weightage, number of questions, key topics and books.
Important syllabus update: By 14th October 2026, the syllabus of JEE Main 2027 has yet to be officially verified as having been published. The syllabus of JEE Main 2026 may be referred to as an interim syllabus in the absence of any publication of the 2027 syllabus by NTA.
Important weightage note: The NTA does not publish the percentage marks distribution of the chapters. The below numbers are estimates of marks distribution from previous year's paper analysis and not guarantees of marks distribution of JEE Main 2027. Question numbers have been estimated based on the 2026 reference pattern of 25 questions per subject.
JEE Main Paper 1 is held for admissions in BE/BTech courses in NITs, IIITs, and other affiliated institutes. This paper evaluates candidates in Physics, Chemistry, and Mathematics.
The syllabus assists students in knowing what topics to cover, whereas weightage analysis gives another method of organizing study. Both need to be considered simultaneously by students instead of choosing some selective chapters.

Importance-wise division of chapters can help students know which topics were regularly asked in past exams. But regularity in the past doesn't mean the same distribution will be in JEE Main 2027.
The following table highlights prominent topic groups from previous-year analysis.
| Subject | Topics to Prioritise for Revision | Preparation Focus |
|---|---|---|
| Physics | Optics, Electrostatics, Current Electricity, Properties of Solids and Liquids, Electromagnetic Induction and Alternating Currents | Concepts, formulas and numerical practice |
| Chemistry | Organic Compounds Containing Oxygen, Coordination Compounds, Hydrocarbons, p-Block Elements, Electrochemistry | NCERT revision, reactions and numerical practice |
| Mathematics | Coordinate Geometry, Integral Calculus, Limits, Continuity and Differentiability, Complex Numbers, Three-Dimensional Geometry | Problem-solving speed, accuracy and regular practice |
The subject-wise tables below provide the historical percentage estimates and corresponding approximate question counts.
Physics involves concepts, formulas, and calculations. An analysis of previous year questions will help students identify topics to be revised early on, however, all topics from the final syllabus must be covered properly.
| Physics Chapter | Historical Weightage (Approx.) | Approx. Questions Out of 25 |
|---|---|---|
| Optics | 8.09% | 2 |
| Properties of Solids and Liquids | 7.16% | 2 |

On the basis of weightage given in the past years, students may give attention to the following areas of study.
Priority 1: Optics, Electrostatics and Current Electricity
Priority 2: Properties of Solids and Liquids, Electromagnetic Induction and Alternating Currents
Priority 3: Magnetism, Oscillations and Waves, Atoms and Nuclei
Priority 4: Complete the remaining Physics syllabus
Don’t ignore topics like Mechanics, Thermodynamics, Gravitation, Measurement, and Experimental Skills merely because of their comparatively lower percentages historically. It is not possible to predict the importance of each topic for the 2027 paper.
The following units are based on the official 2026 reference syllabus and should be checked against the final 2027 document.
Refer to the Official NTA Syllabus for the detailed subtopics.

Below is the list of units that is prepared according to the syllabus provided officially for 2026.
You should refer to the official syllabus to find the topics precisely.
The historical analysis indicates that certain topics need to be covered first while revising. Nonetheless, the last preparation plan must consider the entire syllabus along with the conceptual complexity and personal performance levels.
| Subject | Topics to Consider Early in Revision | Preparation Focus |
|---|---|---|
| Physics | Optics, Electrostatics, Current Electricity, Properties of Solids and Liquids, Electromagnetic Induction and Alternating Currents | Formula application, numerical problems and conceptual questions |
| Chemistry | Organic Compounds Containing Oxygen, Coordination Compounds, Hydrocarbons, p-Block Elements, Electrochemistry and Chemical Bonding | NCERT revision, reactions and numerical questions |
| Mathematics | Coordinate Geometry, Integral Calculus, Limits and Continuity, Complex Numbers, 3D Geometry, Matrices and Determinants | Timed problem-solving, accuracy and error analysis |
Remember: The high historical weightage will not ensure the similar question weightage in JEE Main 2027. It is just an indication and can be used while making the revision schedule.
As of 14 October 2026, the release of the official syllabus of JEE Main 2027 has yet to be confirmed. Thus, there can be no mention of confirmed additions, deletions or changes.
Until the NTA releases the syllabus for 2027, refer to the syllabus of 2026 as your guide. Do not rely on third-party lists of new or deleted topics.
Once the 2027 syllabus is available:
Until the 2027 syllabus is released, use theOfficial JEE Main 2026 Syllabus as a reference. Do not label the 2026 document as the official 2027 syllabus.
Start revision with topics that have appeared frequently in previous years' papers, particularly those that require more practice. After that, proceed to all other prescribed topics to ensure comprehensive syllabus coverage.
Maintain a record of your accuracy percentage and time taken after attempting questions from an entire chapter. If you perform poorly in a chapter that has historically carried significant weightage, give it special attention and practise more questions.
Solve questions from multiple years and shifts wherever available. Categorise your mistakes as conceptual gaps, formula errors, calculation mistakes, or time-management problems. This will help you identify weak areas and improve your problem-solving approach.
Taking mock tests helps you evaluate whether your revision strategy is improving your performance. After each test, identify the chapters in which you made mistakes and revisit the underlying concepts. Adjust your revision priorities based on your results.
Prepare concise notes covering formulas, chemical reactions, key concepts, and common mistakes. Revise these notes regularly throughout your preparation instead of postponing revision until the final stage.
Once the official JEE Main 2027 syllabus is released, review your preparation plan and align your topics with the prescribed syllabus. Until then, use the latest available official syllabus as your reference and avoid relying on unverified claims about syllabus changes.
Chapter-wise weightage is useful for deciding how much time to allocate to different topics during JEE Main preparation. However, it should guide your revision strategy rather than encourage selective study. Give greater attention to high-weightage chapters and topics where you need more practice, but do not neglect the remaining syllabus. A balanced approach that combines topic prioritisation, regular revision, previous-year questions, and mock tests can help you prepare more effectively for the examination.
However, the best method is to combine your syllabus with the past year’s questions.
NTA’s proposed examination schedule suggests that the JEE Main 2027 Session 1 may be conducted in the month of January. You should consider these proposed dates as tentative till the official announcement is made.
