NEET 2019 Chapter-wise wieghtage and Most Important Topics in Biology
Compared to physics and chemistry, biology has high weightage in NEET. Being Biology the simplest subject amongst all three, therefore percentage of questions asked from Biology is 50 %
Based on the NEET Question Paper Analysis of the last 8 years, our expert team has prepared a list of important chapters in biology for the NEET 2019 exam.

NEET hall ticket 2019  has been issued by NTA on April 15 on the NTA official website. Students must download the admit card and should carry it along with them at exam centre for verification purpose. NTA will conduct NEET UG entrance exam on May 5. The exam will be conducted in offline mode.

NEET 2019: Important chapters in Biology

  • In Biology, Ecology is the most important topic for NEET. On an average, 12-15 questions are asked  from this topic every year. This is an easy and the most scoring topic in biology.
  • Human Physiology and Plant physiology are equally important for NEET 2019. Together around 20-25 questions are asked from these two units in the NEET exam.  Your concept should be clear for these two units as more application-based questions are asked in the exam. 
  • Genetics & Evolution is also very important chapter for NEET.
  • Cell structure & Function also carries a good weightage in the NEET exam.

Followings are the important chapters on the basis of  eight years analysis of the question papers.
