NEET 2019: How to score 300+ in Biology?

With only a couple of months left for the National Eligibility Entrance Test (NEET) her is what, how and how much you need to study. Check the detailed preparation strategy by experts to score over 300+ score.

How to get the 300 plus score in the National Eligibility cum Entrance Test (NEET)? Firstly bust the preconceived notions. Most of the NEET aspirants think that Biology is easy, still many do not score enough in this subject to get through government medical colleges. Thousands of them end up scoring between 200 to 230 in Biology. If you are from general category (which means cut-off for government medical college will be 540+), this score in Biology would pretty much end your chances in getting selected in government medical college. National Eligibility Entrance Test-UG is held for medical aspirants for admission in MBBS and dental courses.

Most students find Physics most difficult to prepare for NEET and therefore, devote more time to it. Considering Mathematics is not the core subject (while a few opt it as their fourth subject in class 11 and 12), students face difficulty in solving Physics problems which involve Mathematical concepts such as calculus, trigonometric identities, vectors, etc in solving problems.

While the core to cracking NEET remains in the Biology. Scoring above 310 in Biology requires a thorough understanding of the subject and acknowledging the importance of Biology in your path to 540+ score.

Biology syllabus for the NEET exam can be broadly divided into two parts. Both require a completely different approach to prepare:

Part 1: Factual Biology: Four chapters of diversity in living world, three chapters of structural organization in plants and animals, cell: unit of life, human health and disease (except Immunity portion), evolution (evidence and brief account of evolution), strategies for enhancement in food production and microbes in human welfare.

Total number of chapters: 11+0.5 = 11.5

Total Expected questions (based on past 10 years NEET question paper): 28.

These are going to be fact-based questions straight out of lines of NCERT book. Common mistakes students committee in preparing chapters of Factual

Biology: Students think that they will learn facts in these chapters in the end. In reality, no time remains in the end with the pressure of more difficult things to do. Method to prepare chapters in Factual Biology: Read these chapters from NCERT early in your preparation and prepare fact sheets, for instance, top 50 facts in tissues chapter. Pin these fact sheets in your study room and go through them again and again.

Part 2: Conceptual biology chapter units: Biomolecules, cell cycle and cell division, plant physiology, human physiology, reproduction, genetics and evolution (mechanisms of evolution), biotechnology and ecology

Total Number of Chapters: 26+0.5 = 26.5
Total expected questions: 62
