JEE Main Session 1 represents an important first step toward being admitted to one of the top National Institutes of Technology ('NITs'), the Indian Institute of Information Technology (‘IIITs’), or other premier engineering institutes. JEE Main Admission Process has a very high level of competition, and the JEE Main syllabus has been established for several years now; thus, students must develop a structured approach to the overall process of preparing for JEE Main by implementing a systematic, efficient plan until they sit for Session 1 of JEE Main.
Due to the increase in demand for engineers, the economy and the number of people wanting to get into an engineering career, there has also been a significant increase in the amount of material being taught in schools across India. Therefore, while most people studying for the JEE Main will be reading from different sources of study material (which include many NCERT textbooks and many other books), many students are going to be studying primarily from NCERT texts. So it is very important that students revise the content from the NCERT textbooks as accurately and clearly as possible, focusing extensively on what they have already studied in the NCERT textbooks before studying from any other sources of material. From my experience, it is the best way to prepare for JEE Main and perform well in JEE Main Session 1.
Why NCERT Is a Game-Changer in JEE Main Session 1
NCERT textbooks have always been the backbone of JEE Main preparation, but their importance becomes even more critical during the final revision phase of Session 1. Over the years, exam trends have shown that many NCERT-based questions in JEE Main are either directly lifted from NCERT lines or are conceptually framed around its examples, diagrams, and definitions. This makes NCERT not just a study resource but a strategic tool for scoring well in the exam.
What “NCERT-based questions” really mean
NCERT-based questions do not always mean word-for-word repetition. Instead, they include questions based on NCERT concepts, diagrams, tables, graphs, exceptions, and solved examples. Many times, JEE Main questions reframe NCERT statements into application-based problems, testing how deeply a student has understood the text rather than how much they have memorised.
Which Subject Is the Most Dependent on NCERT?
Of the three subjects, that is Chemistry (with Inorganic Chemistry), Physics, and Mathematics, Chemistry has the greatest amount of dependency on NCERT when compared with Physics and Mathematics. The bulk of questions on Chemistry for JEE will require you to know and use information found within the NCERT textbooks. The bulk of questions for Physics come from NCERT, with a lesser amount of Physics-based questions needing to be derived from NCERT-created diagrams. Mathematics relies on NCERT textbooks to teach students the fundamental concepts, but the practice piece of Maths is by far the most critical.

Session 1 timeline context
As JEE Main Session 1 is held in January, students tend to be at the very end of their preparation process and will be focusing on revising rather than studying new material. Thus, JEE Main Session 1 revisions should be timed correctly, and therefore, all of the hours spent preparing for JEE Main Session 1 should be dedicated to high-yield/revision of NCERT materials from previous years as opposed to searching for new references or new reference materials.
The real goal of your final revision
The objective of final preparation should be simple: maximise accuracy while minimising mistakes. This is best achieved through an NCERT-first approach combined with systematic PYQ practice and mock tests. If your revision is structured around JEE Main NCERT topics, you are more likely to avoid conceptual confusion and perform confidently on exam day.
First NCERT Revision Framework for JEE Main 1
A limited time until JEE Main 1 means the revision approach should be methodical rather than haphazard. Many students incorrectly assume that repeatedly looking at numerous books, watching endless videos on YouTube or doing many mock test runs does prepare them adequately for the exam. The better way to prepare is with an NCERT-first revision plan based on conceptual understanding, syllabus fitting, and exam-ready preparedness. A focused reading of the NCERT, a detailed note-booking system of the concepts from the NCERT and an evaluation of previous year's questions are three pillars to achieving the goal of effective, high-yield JEE Main 1 revision.
Smart NCERT Reading
The process of preparing for the JEE requires an active rather than passive reading of the NCERT textbook. When reading through a chapter, highlight the key terms, definitions, formulas, key concepts/trends, etc., using a key for the highlighter as you go along. Pay special attention to the tables, chemistry reaction conditions, physics derivations and mathematics standard results. Each line of the NCERT textbook should be viewed as potentially examinable material for NCERT-based questions on the JEE Main exam.
Create short, condensed notes from NCERT.
Condensing chapters into one-page notes using NCERT after thinking about the chapter will allow you to keep track of important formulas, major concepts, tricky exceptions, and frequently asked questions from within that chapter. You can use these notes to assist your memory and confidence before exams as a quick way to refer to what you learned about that chapter. When you need a reminder of everything you studied about a particular chapter, you can quickly scan through these one-page notes.
NCERT then Previous Year's Questions (PYQs) then Mock Tests
After studying any chapter from the NCERT, make sure you look through the JEE Main previous years' questions on that topic to see how the concepts in that chapter have been used in the JEE. After going through ALL the PYQs for the chapter, try completing either sectional or full mocks as well to help simulate the exam experience and improve your speed and accuracy.
Chemistry Most NCERT-Based Topics to Revise for JEE Main Session 1
The JEE Main Chemistry paper is considered the most dependent on the NCERT textbook (National Council of Educational Research and Training) and therefore, if you prepare/ revise properly, it can definitely be one of the easiest sections to score in. A majority of all the NCERT-based questions that come up in the JEE Main exam for Chemistry (especially Inorganic and Organic Chemistry) are either exactly taken directly from NCERT or can be answered using the statements in NCERT along with reaction conditions, reaction diagrams, reaction tables or by the conceptual approaches discussed in NCERT.
During the preparation of JEE Main Chemistry Section 1, it is important to focus on clarity, accuracy, and long-term memory retention rather than just speed.
Inorganic Chemistry (NCERT - The Holy Book)-
Inorganic Chemistry is predominantly NCERT-based, and therefore, there are many concept, direct-type questions based on Inorganic Chemistry.
- Periodic Trends: Revise how atomic radius, electronegativity, ionisation energy and electron affinity trends occur on the periodic table, including exceptions as given by NCERT.
- Chemical Bonds - Revise the VSEPR shapes, Hybridisation, the character of the bond and the geometrical structure of molecules.
- Coordination Compounds: When revising Coordination Compounds, focus on NCERT nomenclature, isomerism (structure), crystal field theory and magnetic properties. All these topics are very high-yield items in JEE Main Chemistry.
- p-Block Elements: Pay close attention to the properties, reactions and important compounds as they are presented within the p-block section of NCERT.
- d and f Block Elements: Revise colours, oxidation states and general chemical reactivity of Transition Elements.
A smart strategy is to read NCERT line-by-line for Inorganic and cross-check each concept with PYQs.
Concept plus Mechanism Matters of Organic Chemistry
To fully understand Organic Chemistry, you'll need to read through the NCERT book and apply those concepts.
General Organic Chemistry (GOC): You should review inductive effect, resonance, hyperconjugation, acidity and/or basicity trends.
- Hydrocarbons and Haloalkanes: Concentrate on the reaction mechanisms, different stability trends, and important reagents.
- Alcohols, Phenols, and Ethers: The conditions of the reactions, as listed in NCERT, are very important to your understanding.
- Aldehydes, Ketones, and Carboxylic Acids: Many of the questions you will encounter in this unit will be similar to those in the NCERT book or follow named reactions.
- Amines, Biomolecules, and Polymers: All of these are usually based directly on the NCERT book, and so are relatively easier to score on.
Formula plus Concept Balance of Physical Chemistry, whereas for Physical Chemistry understanding and application are a greater measurement than memorisation.
Mole Concept plus Redox Reactions: Review stoichiometry, oxidation numbers and balancing reactions.
- Thermodynamics plus Equilibrium: Review the formulas and assumptions, and learn to interpret graphs.
- Electrochemistry plus Solutions: Study conductivity, molarity and colligative properties.
- Chemical Kinetics plus Surface Chemistry: The definitions and graphs found in NCERT are recurrent in JEE Main.
If your NCERT foundation is strong enough and you have thoroughly practised with the PYQs, Chemistry is likely to be your best-scoring subject during JEE Main Session 1.
Physics in the JEE Main exam is formula-driven and heavily relies on understanding the underlying concepts. Having a good NCERT background will be a big advantage for many students in terms of both accuracy and confidence during the exam. Many of the NCERT based questions, especially those focusing on conceptual/theoretical/graph-based concepts, are based directly upon the NCERT derivations, and examples can be found within the NCERT textbook.
Your Physics goals for an effective JEE Main Session 1 revision will be strengthening your understanding of the concepts, minimising the mental confusion created by many formulae, and improving the speed with which you can solve problems.
The conceptual basis of Class 11 Physics
The Class 11 Physics course contains fundamental principles of many advanced topics that will be taught in Class 12, so Class 11 Physics must not be omitted from your final revision.
- Units, dimensions, and Errors: A simple chapter for scoring quick marks, as most of the NCERT Theory corresponds directly to JEE Questions.
- Kinematics and Laws of Motion: Review relative motion, graphs, and free body diagrams.
- Work, Power, and Energy: Beyond conservation of energy laws, their energy relations are explained in the NCERT.
- Rotational Motion: Know your moment of inertia equations and parallel and perpendicular axes theorems.
- Gravitation: Review orbital mechanics and gravitational potential.
- Thermodynamics & Kinetic Theory: NCERT diagrams and assumptions are highly examinable.
- SHM & Waves: Conceptual clarity is more important than speed here.
Class 12 Physics — High-Scoring If Revised Properly
Class 12 Physics carries significant weight in JEE Main, and NCERT plays a crucial role in conceptual clarity for JEE Main Physics.
- Electrostatics & Current Electricity: Revise electric field lines, potential, and circuit concepts from NCERT.
- Magnetism, EMI & AC: Many questions are based on NCERT derivations and graphs.
- Ray Optics & Wave Optics: Focus on lens formula, interference, and diffraction patterns.
- Modern Physics: This is one of the most NCERT-dependent sections and highly scoring.
- Semiconductors & Communication Systems: A quick revision from the NCERT can secure easy marks.
How to Revise Physics in the Last Days
Instead of solving hundreds of new problems, revise your formula sheet daily, revisit NCERT diagrams, and analyse your past mock test mistakes. Chapter-wise PYQs combined with NCERT reading is the most reliable approach for jee main session 1 revision.
A well-structured NCERT-based Physics revision will help you reduce conceptual errors, improve speed, and score consistently in Session 1.
Mathematics - Important Concepts of NCERT in Preparation for JEE Main Session 1
Mathematics sections of JEE Main are very practice-based and require students to understand the concepts of the subject thoroughly. It will help the student improve his or her speed when answering questions and will also reduce errors. Many students rely solely on coaching material; however, students with a good grasp of NCERT topics will have a better chance of seeing the same type of question again and therefore, will be more likely to use the right formulas to solve them without falling into common pitfalls. During jee main session 1 revision, your Maths strategy should focus on formulas, standard results, and timed PYQs rather than learning new techniques.
Algebra — High-Scoring with Smart Practice
Algebra forms a major portion of the JEE Main Maths syllabus and is conceptually rooted in the NCERT.
- Quadratic Equations & Sequences and Series: Revise discriminant, sum and product of roots, and standard series results.
- Complex Numbers: Focus on geometric interpretation, modulus, and argument.
- Matrices & Determinants: NCERT properties, shortcuts, and determinant rules are frequently tested.
- Permutation & Combination and Probability: Standard counting techniques and basic probability formulas should be crystal clear.
- Binomial Theorem: Revise expansions, term coefficients, and basic applications.
A strong grasp of NCERT concepts here can significantly boost your accuracy in moderate-level questions.
Calculus — The Core of JEE Maths
Calculus is one of the most important and scoring areas in JEE Main.
- Limits, Continuity, and Differentiability: Understand standard limits and conceptual reasoning from NCERT.
- Application of Derivatives: Revise maxima-minima, tangents, and rate of change problems.
- Indefinite and Definite Integrals: Focus on standard integrals and substitution techniques.
- Area Under Curves & Differential Equations: NCERT-based basics often appear in direct questions.
Instead of memorising shortcuts, focus on conceptual understanding to handle both easy and tricky problems.
Coordinate Geometry & Vectors/3D
This section is formula-driven but concept-based.
- Straight Lines, Circles, and Conics: Revise standard forms, focus-directrix concepts, and geometric interpretation.
- Vectors & 3D Geometry: Pay attention to dot product, cross product, and line-plane relationships.
Practising chapter-wise PYQs after NCERT revision is the best way to master this section.
How to Revise Maths in the Final Days
In the last phase of JEE Main session 1 revision, avoid learning new topics. Instead, revise formula sheets daily, solve mixed PYQs, and practice time-bound tests. Track your weak areas and focus more on accuracy than speed.
A disciplined NCERT-based Maths revision combined with consistent practice can help you maximize your score in JEE Main Session 1.
15-Day JEE Main Session 1 Revision Plan (NCERT + PYQ + Mock)
With limited time left before JEE Main Session 1, a well-structured 15-day plan can make a significant difference in your performance. Instead of random revision, this plan follows a systematic approach that prioritizes jee main ncert topics, chapter-wise PYQs, and regular mock analysis to ensure maximum retention, accuracy, and confidence.
Days 1–5 — NCERT-Centered Concept Consolidation
The first five days should focus on a thorough NCERT revision combined with short notes.
- You will be concentrating on completing the entire NCERT syllabus for Chemistry (Inorganic and Organic) during the first five days, along with creating short notes that you can use.
- You will complete all of the Inorganic and Organic Chemistry chapters using NCERT and creating a short list of important reactions, trends, and exceptions in your revision book as you complete the revision of those two chapters.
- The same approach will be used in Physics for the theory and diagrams used in the previous chapters to complete the NCERT syllabus of the most important chapters; Mechanics, Electrostatics, and Magnetism.
- For Mathematics, you will complete your revision of all of the NCERT-based concepts and formula sheets related to Algebra and Calculus.
Days 6–10 — PYQ-Driven Practice Phase
These five days should be completely question-oriented.
- Solve previous years’ questions subject-wise and chapter-wise under timed conditions.
- Identify weak areas and revisit NCERT concepts for those chapters.
- Maintain an error log and update it daily with conceptual mistakes and silly errors.
- Take at least one sectional mock every alternate day.
Days 11–15 — Full-Length Mocks & Deep Analysis
The final five days should be dedicated to exam simulation and refinement.
- Attempt 4–6 full-length JEE Main mock tests under real exam conditions.
- Spend at least 60–70% of your time analysing mistakes rather than solving new questions.
- Revise your formula sheets daily, especially for Physics and Mathematics.
- Do a quick NCERT skim for Inorganic Chemistry and Modern Physics.
By following this structured JEE Main Session 1 revision plan, you can strengthen your conceptual clarity, reduce careless mistakes, and enter the exam hall with confidence and readiness.
Conclusion
JEE Main Session 1 assesses your ability to quickly revise material as well as your level of knowledge. Although there is no substitute for doing practice/mock tests, as far as being successful on exam day is concerned, success will ultimately depend on how well you have a grasp of the basic concepts of the JEE syllabus—most of which are acquired from NCERT books. By conducting a strong, focused revision of the JEE Main syllabus topics according to the NCERT books and matching this strong revision with the review of chapter-wise previous year question papers (PYQs) as well as a properly planned analysis of your performance in mock tests, you can greatly enhance your accuracy, speed and confidence during the JEE Main exam
