| 95 percentile | 130 – 150 marks |
| 90 percentile | 110 – 125 marks |
High-Weightage and Easy Topics – Start with preparing with chapters like Modern Physics, Atomic Structure, Chemical Bonding, and Probability. These topics don't take more time and carry significant weight, which helps you to get 100+ marks early.
Practice All Three Subjects Daily – Don’t study only one subject the whole day. Rather, multiple subjects every day: Chemistry in the morning, Maths in the afternoon, and Physics in the evening as per JEE Mains 2026 syllabus. This will help you make your brain flexible and ready for the JEE paper.
Technology and Online Test Platforms – Take daily mock tests on CBT platforms or coaching portals. If you practice on a computer, it improves speed, which will provide digital comfort, and lets you check weak areas with performance tracking tools.
Mental Strength and Exam Temperament – Train your mind by solving tests in little stressful or noisy situations, create a proper sleep cycle aligned with exam timings, eat light prior to practice tests, and create the habit of skipping lengthy problems and revisiting them after some time. This will be beneficial to reduce little mistakes and improve accuracy under pressure.
Stay Calm in Exam Hall – Control stress with deep breathing and positive thoughts. Panic leads to silly mistakes and poor time management.A calm mind ensures fewer silly mistakes and higher accuracy.
Health & Routine- Fix your sleep cycle at least 2 weeks before the exam. Eat light, stay hydrated, and avoid last-minute stress. A healthy routine keeps your brain sharp on exam day.

Create a realistic and achievable study plan based on your strengths and weaknesses. Allocate sufficient time to cover each subject thoroughly. Ensure that you have enough time for revision and solving practice papers. Break down your study schedule into smaller, manageable goals to track your progress.
Focus on building a strong foundation in fundamental concepts. JEE Mains questions are designed to test the depth of your understanding rather than rote memorization. Devote time to each topic, practicing problems of varying difficulty levels. Utilize standard reference books and study materials recommended by experts. Here are some reference books that you can go through:
|
Physics: Concepts of Physics by H.C. Verma |
Chemistry: Physical Chemistry by O.P. Tandon |
|
Mathematics: IIT Mathematics by M.L. Khanna |
Physics: Problems in General Physics by I.E. Irodov |
