Do or die chapters for NEET 2025: Weightage, Physics, Chemistry, Biology Preparation

Do or die chapters for NEET: NEET (National Eligibility cum Entrance Test) is one of the most competitive medical entrance exams in India, and it requires thorough preparation to crack it. As the NEET exam approaches, it is essential to prioritize the chapters that can be the make-or-break ones for a candidate’s success. These are commonly known as the “do or die” chapters. NEET 2025 do or die chapters will help candidates in their aim to crack India’s single-largest medical exam. Admission to 97293 MBBS, 27868 BDS, 52,720 AYUSH (BAMS /BHMS/ BUMS/ BSMS/ BNYS), 603 BVSc, and AH seats will be granted based on the NEET scorecard. In 2025, admission to BSc nursing and life science courses will also be based on NEET scores.

Medical students who want to become doctors take the entrance exam without knowing the NEET 2025 do or die chapters, which contain more questions. This makes it more difficult for people to score well on the NEET exam. In this article, we will discuss some of the most important Do or die chapters for NEET 2025, candidates can check the subject-wise important chapter to crack the NEET 2025 exam.
