Preparation for JEE (Main and Advanced) requires hard work, dedication, and proper planning. To start with, students should have a clear understanding of the syllabus, exam pattern, and weightage of different topics. It's recommended to have a good grip on class 11th and 12th CBSE syllabus. Solving previous years' papers and taking mock tests can help students understand the level of difficulty and improve their time management skills. Regular practice of mathematics, physics, and chemistry problems is essential. It's also crucial to stay updated with current affairs, as some questions from general knowledge can also be asked in JEE. To keep their concepts clear, students should regularly revise what they have learned and clarify their doubts with their teachers or mentors. A balanced approach towards studies and self-care is crucial to achieve success in JEE.
