For NEET exam, NEET 2022 Biology important topics are the cream of your biology preparation. Many of the aspriants unaware about the NEET 2022 Biology important topics from which maximum questions are asked, definitely makes the preparation more tedious. As NEET is the only entrance exam for granting admission in medical college and one of the most competitive exam in India, you should prepare smartly & strategically to make confident about performance in the exam paper.
Why NEET 2022 Biology important topics can’t ignore?
Biology is the most score-making section in the NEET Questions Paper, because it comprises 100 questions out of total 200 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 most important 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.
