Biology Weightage For NEET 2021

NEET is a national level, single entrance exam for medical aspirants carried out every year for admissions to medical institutes. The exam assesses students’ knowledge in different sections such as Physics, Chemistry, and Biology. The exam is carried out for 720 marks, with 360 marks alone allotted for the Biology section. In other words, 90 questions appear in the Biology section of NEET, 45 each from Botany and Zoology sections.

Over the years, on average, it has been observed that the Biology section of NEET exam is typically the easiest. Students find this section to be easy as 80-85% of questions appearing from this section in the NEET-UG exams are directly picked from the NCERT syllabus.

Only a mere 15% or so questions in the NEET Biology section are beyond the scope of NCERT. Hence, candidates who are well-versed with every line of the NCERT textbook for Biology are assured to crack the NEET Biology section with flying colours. To assist students in this endeavour further and comprehend the importance of concepts, we bring to you chapter wise weightage of Biology concepts as the NEET Biology syllabus remains vast.
