Day-to-day Preparation Tips to Score 99 Percentile in JEE Main 2026

Based on the expert insights and topper’s suggestions, below are practical day-to-day tips to help you score 99 percentile in JEE Main 2026:

  • Try to solve at least 50 questions every day from Physics, Chemistry, and Mathematics. Focus on solving them quickly and correctly. Regular practice with previous years’ JEE questions and mock tests will help you get used to exam patterns and improve your time management skills.
  • Make sure your basics are strong, especially in NCERT textbooks, as many Chemistry questions come directly from them. Keep short notes of important formulas, shortcuts, and key points. These notes will be very useful for quick revisions, especially in the last few weeks before the exam.
  • Plan your study time wisely. Give extra time to subjects or topics you find difficult. A simple daily schedule can help: for example, study Physics in the morning, Mathematics in the afternoon, and Chemistry in the evening. This kind of routine makes preparation smoother and less stressful.
  • Take a full mock test every week to check where you stand. After each test, spend time analysing your mistakes, improving your speed, and making sure you don’t repeat errors.
  • Use your JEE Main 2026 Mock Test results to identify weak topics. Spend more time practising and revising these areas. Targeted practice is the key to turning weak points into strong ones.
  • Practice completing mock exams within the real 3-hour time limit. Divide your time properly between Physics, Chemistry, and Math. Also, maintain good sleep, eat well, and stay motivated.
  • Keep yourself motivated every day. Visualise your goals and track your progress. Stay positive, remain consistent, and remember that preparation is a continuous journey, not a one-day effort.

Following these daily strategies with focus, discipline, and a smart approach can significantly improve your chances of scoring 99+ percentile in JEE Main 2026.
