Hello Prashant,

To score well in NEET 2025, start by thoroughly understanding the syllabus. Focus on NCERT books for Biology, Chemistry, and Physics, as they are the foundation for NEET. Ensure you cover every chapter and pay special attention to high-weightage topics like Human Physiology, Genetics, Organic Chemistry, and Mechanics, as these are frequently tested in the exam.

Create a structured study plan and allocate specific time for each subject daily. Be consistent with your schedule and dedicate time for practice, revision, and mock tests. It’s crucial to solve previous years’ NEET question papers and sample papers to familiarize yourself with the exam pattern and improve your time management skills.

Identify and work on your weak areas by dedicating extra time to those subjects or topics. If necessary, seek guidance from teachers, online platforms, or coaching institutes. Regularly revise the NCERT textbooks, especially for Biology, as it carries the highest weightage in the exam.

Consistency is key. Studying daily and focusing on understanding concepts rather than rote memorization will make a significant difference. Additionally, maintain a balanced lifestyle, eat healthily, and ensure you get 7-8 hours of sleep each night to stay focused and energized.

By following a well-organized study plan and staying disciplined, you can significantly improve your chances of achieving a high score in NEET 2025.
