NEET-UG 2021 is the only entrance exam for granting admission in medical college, it is one of the most competitive exam in India. So, one should prepare smartly & strategically to make confident about performance in the exam paper. Many of the aspriants unaware about Do or Die topics in Biology for NEET 2021 from which maximum questions are asked, definitely makes the preparation more tedious.
Why Do or Die Topics in Biology for NEET 2021?
Biology is the most score-making section in the NEET Questions Paper, because it comprises 90 questions out of total 180 questions. So only Biology, covers half of the total score (360 out of 720). But the problem is the Biology Syllabus of NEET. A huge syllabus including 10 Units, 38 Chapters with so many Topics, which make tiresome in the preparation. Many aspriants are bewildered to revise the whole syllabus repeatedly prior to the exam. Here I discuss all the “Do or Die topics” from every chapters of Biology from where maximum questions are frequently asked in NEET. So you can not ignore this topics at any cost to make scores above 320.
