Eliminate Options: For multiple-choice questions, use elimination techniques to improve your chances.
Avoid spending more than 2–3 minutes on any question to ensure you complete the paper.

5. Prioritise JEE Main Previous Year Papers

Solving past JEE Mains PYQs is one of the most effective ways to understand the JEE exam pattern and question trends.

Go through the last 10 years’ question papers and solve them under timed conditions.
Pay attention to recurring topics like Mechanics, Calculus, and Coordination Chemistry.
Use these papers to refine your understanding of how to prepare for JEE Mains and tackle questions efficiently.

6. Manage Your Study Hours Effectively

If you are wondering “How many hours to study for JEE Mains” it depends on your understanding of topics and consistency. Ideally, aim for 8–10 hours of focused study each day. Remember to include short breaks between study sessions to stay fresh and focused.

Morning: Revise important topics from Physics and Mathematics.
Afternoon: Dedicate time to Chemistry, especially NCERT-based revision for Inorganic Chemistry.
Evening: Solve practice problems and take mock tests.
Night: Go through error analysis and revise formulas or reactions.

7. Revise Formulas and Key Concepts Daily

JEE Main is heavily formula-based, especially in Mathematics and Physics. Dedicate time every day to memorising and revising essential formulas.

Maintain a formula notebook for quick reference.
Focus on derivations and shortcut techniques for problem-solving.
For Chemistry, revise periodic trends, reaction mechanisms, and Physical Chemistry formulas regularly.

8. Practise Time and Stress Management Techniques

Stress is common during preparation for JEE Mains, but learning to manage it is crucial for success.

Include relaxation techniques like meditation or light exercise in your routine.
Avoid overthinking or comparing yourself with others; focus solely on improving your performance.
Stick to a disciplined routine and trust your preparation.

9. Strengthen Conceptual Understanding in Physics

Physics is concept-heavy, and strong fundamentals can help you tackle tricky questions. Focus on:

Visualising concepts using diagrams and graphs.
Revising important experiments, such as Young’s Double-Slit Experiment and Wheatstone Bridge.
Practising numerical problems regularly to strengthen application skills.

10. Deepen Focus on Chemistry NCERT

NCERT is the most reliable source for Chemistry, particularly Inorganic and Organic Chemistry.

Memorise reactions, equations, and block trends directly from NCERT books.
Practise reaction-based problems from Hydrocarbons, Coordination Compounds, and p-block elements.
Use NCERT Exemplar problems for added practice.

11. Maintain Consistency in Mathematics Practise

Mathematics requires consistent problem-solving to master:

Solve 100–150 problems daily from high-weightage chapters like Calculus, Probability, and Trigonometry.
Practise graphs and visual approaches for Coordinate Geometry.
Regularly revisit weaker topics and track improvements.

12. Plan a Structured Revision for the Final 3 Days

In the last three days, focus on revising high-yield content rather than exploring new topics.

Revise flashcards or short notes you’ve prepared.
Solve one full-length test daily to stay in exam mode.
Stay calm, and don’t overexert yourself during these final days.

How to Attempt JEE Mains Exam Paper?

Cracking JEE Mains requires not just strong subject knowledge but also a smart approach to attempting the paper. Here's a detailed guide to help you tackle the exam efficiently:

1. Read the Instructions Carefully
Before you start, spend 2–3 minutes reading the exam instructions thoroughly. Ensure you understand:

The marking scheme (positive and negative marking).
The time limit for the exam (3 hours).
The structure of the paper (Physics, Chemistry, and Mathematics sections).

2. Start with Your Strongest Subject
Begin the paper with the subject you are most confident in. This builds momentum and boosts confidence early in the exam. For example, if you excel in Mathematics, tackle that section first before moving on to Physics or Chemistry.

3. Follow the “Easy to Difficult” Strategy
Scan each section quickly to identify easier questions. Attempt those first to secure marks quickly, and then move on to medium and difficult ones. Avoid wasting time on lengthy or challenging questions at the start. Mark the tough questions for review and revisit them later if time permits.

4. Manage Your Time Efficiently
Time management is critical in JEE Mains. Allocate a fixed amount of time to each section:

Mathematics: 60 minutes
Physics: 50 minutes
Chemistry: 50 minutes
Reserve 20 minutes for reviewing marked questions or rechecking. Stick to these time limits to ensure you can attempt all sections.

5. Prioritise Accuracy Over Speed
It’s better to solve fewer questions correctly than to rush and make mistakes. Avoid guesswork, especially if you’re unsure about an answer. Random guessing can lead to negative marking. Use elimination techniques for multiple-choice questions to improve accuracy.
