NEET is a national-level entrance exam conducted each year for medical aspirants seeking admission to medical institutes. The exam evaluates students' knowledge across three subjects: Physics, Chemistry, and Biology.
Biology alone covers 50% percent of NEET Exam with a total of 90 questions (45 from Zoology and 45 from Botany). Applicants need to attempt all the questions as per new guidelines of NTA (Section A: 35 compulsory questions. Section B: 10 questions).
Seeing the past year's trends, the Biology section of NEET is generally considered the easiest. This is primarily because 80-85% of the questions in NEET-UG were directly sourced from the NCERT syllabus. Only about 15% of the questions are beyond the scope of NCERT. Therefore, candidates who thoroughly study the NCERT Biology textbook have a significant advantage in excelling in this section.
There used to be 97 chapters before, but now it has been reduced to 79 chapters. There is no change in the unit numbers, NEET aspirants still have to prepare 10 units for their upcoming NEET examination.
