As JEE Main 2026 is fast approaching, many aspirants are time-bound to finish the vast syllabus, apply problem-solving methods efficiently, and to be accurate. With such stiff competition, it is common to feel to feel overwhelmed. But what if you could be able to study smart, not hard?
The first step in achieving this is by aiming for the most important chapters, or chapters of the syllabus that have historically held maximum weightage, as presented in previous years’ question papers. So if you are limited for time, or are revising in the weeks leading up to the exam, targeting this material is much more likely to help with your success rate and all India Rank (AIR).

Strategy Tips for Final Month Preparation
- Prioritize revising important chapters: Refer to the high-weightage list above.
- Practice PYQs (previous year questions): This will help you identify trends in questioning.
- Mock tests: Take 1 full-length mock test every second day.
- Time management: Use 3-4 hours per subject per day.
- Focus on accuracy instead of trying to attempt everything.
- Use NCERT for Chemistry: Particularly useful for Inorganic.
You should emphasize on chapters like Calculus, Coordinate Geometry, Vector 3D, and Probability to chalk [determine] your syllabus, as they show a higher occurrence and are riveting in terms of scoring scope.
No, there are some topics that will [have] a greater weightage like Modern Physics, Current Electricity, and Electrostatics. Prioritize them but revise all the topics anyway for safety.
Organic Chemistry holds a fair portion of the Chemistry paper. Remember, you should emphasize topics like Named Reactions, GOC, and Hydrocarbons.
Coaching material would be . You have to rely on reference materials such as HC Verma, Cengage, or previous years questions so that you have a more profound understanding.
Generally chapters like Surface Chemistry, Environmental Chemistry, and the Chemistry in Everyday Life would have fewer questions, it could be risky to omit these chapters.
