The JEE Main exam is conducted by the National Testing Agency (NTA), a government body that looks after many entrance tests across the country. Every year, lakhs of students appear for JEE Main with the hope of getting a good college and in the field of technology or engineering. In 2025, around 15.39 lakh students registered across both sessions and over 14 lakh students appeared for the exam. Students who have passed or are appearing for Class 12th with Physics, Chemistry, and Math are eligible to give the JEE Main exam. The exam is held twice a year in January and April (candidates can appear in both and the best score is considered), and the mode of the exam is Online (Computer-based Test).
JEE Mains 2026 – Highlights
JEE Main is not just another school exam. It’s a gateway to India’s top engineering institutes like the NITs, IIITs, and other government-funded colleges which is conducted by the National Testing Agency (NTA). Candidates can take admission in three courses through JEE Main, which are:
| PAPER | SUBJECTS | TOTAL MARKS |
| B.E. or B. Tech Students | Physics, Chemistry and Mathematics | 300 |
| B. Arch (Architecture Students | Maths (online), Aptitude (online), Drawing (offline) | 400 |
| B.Planning | Maths, Aptitude, and Planning-based questions | 400 |
The exam duration is 3 hours, and language options offered are English, Hindi, Gujarati, Bengali, Tamil, Telugu, Marathi, Urdu, Kannada, Malayalam, Odia, Assamese, and Punjabi.
JEE Main 2026 – Important Subjects for Class 11 & Class 12
For starting JEE Main preparation in Class 11 or 12, knowing which topics carry more weightage can help candidates focus better.
Class 11 Important Topics:
| PHYSICS | CHEMISTRY | MATHEMATICS |
| Motion in a Straight Line | Some Basic Concepts of Chemistry (Mole Concept) | Sets, Relations and Functions |
| Laws of Motion | Atomic Structure | Trigonometry |
| Work, Energy & Power | Equilibrium | Permutations and combinations |
| Rotational Motion | Redox Reactions | Sequences and series |
| Thermodynamics | Chemical Bonding | Coordinate Geometry and Straight lines |
Class 12 Topics to Focus On:
| PHYSICS | CHEMISTRY | MATHEMATICS |
| Current Electricity | Electrochemistry | Calculus ( Limits, Derivatives, Integrals ) |
| Electromagnetic Induction | Chemical Kinetics | Vectors and 3D geometry |
| Alternating Current | Coordination Compounds | Probability |
| Modern Physics | Organic Chemistry (Reactions, Mechanisms) | Matrices and Determinants |
| Ray and Wave Optics | Biomolecules and Polymers | Application of Derivatives |
JEE Main 2026 – When to Start & What to Study NCERT First, References Later
The ideal time to begin the JEE Main preparation is Class 11, when most of the new topics are first introduced. Starting early gives a major advantage, like more time to understand core concepts.
Candidate’s priority should be the NCERT textbooks as they cover the basics clearly and are often the source for many direct questions in the JEE Main exam. Whether it’s Physics formulas, Chemistry reactions, or Math theorems, mastering NCERT builds a strong base.
Once candidates are confident with NCERT, they can slowly move to reference books like Physics: H.C. Verma or D.C. Pandey, Chemistry: O.P. Tandon, N. Awasthi (for Physical), or MS Chauhan (for Organic), Maths: R.D. Sharma, Cengage, or Arihant series.
JEE Mains Study Plan: Physics, Chemistry, Mathematics
| Study Task | Physics | Chemistry | Mathematics |
| Theory Revision | Read 1 chapter (from NCERT + notes) | Revise 1 chapter (Organic/Inorganic/Physical) | Study 1 concept (Functions, Calculus, etc.) |
| Practice Questions | Solve 10–15 Numerical | Solve 15–20 MCQs (mix of easy & tricky) | Solve 20 problems (basic to JEE Main level) |
| Previous Year Questions (PYQs) | Solve topic-wise PYQs | Attempt PYQs for revised chapter | Solve past year questions from same topic |
| Formula Recap | Revise formulas with a sheet or flashcards | Review reactions, exceptions, name reactions | Go through identities, theorems, and key tricks |
| Quick Revision or Light Topic | Revise previous topic (lightweight) | Go through Environmental / Chemistry in Everyday Life | Recap Sets, Statistics, or similar light topics |
| Doubt Resolution / Notes Update | Clarify any stuck concept via YouTube or book | Update short notes or flashcards | Make formula map or revise rough notes |
| Mini-Test (Optional) | 15–20 questions mixed quiz | 20-minute chapter quiz | Timed problem set from test series |
JEE Mains 2026: Common Mistakes Most Students Make
While preparing for JEE Main, many students unknowingly make mistakes that slow down their progress and reduce the chances of admission. One of the most common errors is starting late. Beginning in Class 12 or just a few months before the exam leaves little time for deep understanding and revision, and there is more pressure from 12th exams and JEE mains too, which leads to heavy pressure and stress. Starting in Class 11 allows you to study calmly and cover topics more thoroughly.
Another mistake is ignoring the NCERT textbooks. These are often underestimated, especially in Chemistry, students avoid NCERT books thinking it’s less important or easy, but many JEE questions come directly from them. Jumping to tough reference books too soon can cause confusion and demotivation if your basics aren’t clear.
Some students study without any plan, focusing more on one subject and neglecting others. A simple, balanced routine helps avoid this. Others try to memorize formulas without understanding the logic behind them, which doesn’t work in JEE, where concepts matter most.
Skipping mock tests or past papers is another misstep. These help you manage time as you have to attend all the questions within 3 hours. Avoiding these small mistakes can make preparation smoother and more effective.
