With the maximum number of marks, the NEET biology syllabus is the most important area to score high. Medical candidates aiming to crack the medical entrance test with ease should know the NEET 2022 Biology syllabus thoroughly. The Biology syllabus of NEET consists of two important sections, Botany and Zoology. Each section contains 50 marks out of which 45 questions need to be attempted which results in 360 marks in NEET total marks.
Also, refer to the NEET-UG Physics syllabus 2022.
Candidates with a better concept clarity of the Biology syllabus can score well in the NEET exam. NEET Biology syllabus 2022 carries an almost equal weightage of questions from Classes 11 and 12. So, aspirants are required to go through the full syllabus of NEET Biology for a better result.
The NEET 2022 biology syllabus consists of lots of biological scientific terms and facts which are to be remembered, so aspirants have to prepare according to that. Read the article on the NEET biology syllabus 2022 to know the class-wise syllabus, chapter-wise biology weightage, important topics, best books, preparation tips, and all other relevant information.

Frequently Asked Questions (FAQs)
Question:- What is the NEET exam?
Answer:- The National Eligibility Entrance Test (NEET), formerly the All India Pre-Medical Test (AIPMT), is the qualifying test for MBBS and BDS programs in Indian medical and dental colleges. It is conducted by the National Testing Agency (NTA).
Question:- What is the difference between MBBS and NEET?
Answer:- NEET exam is important because it is the only medical entrance exam conducted in India. This includes the admission to MBBS courses in all government medical institutes and also the admissions to AIIMS and JIPMER. As entrance examinations to AIIMS and JIPMER have been replaced by NEET.
Question:- What is NEET good for?
Answer:- Through NEET, students get admission to numerous medical courses, namely BDS, MBBS, AYUSH (BAMS, BUMS, BHMS), etc. Seats for these courses are available in private and government colleges. National Testing Agency (NTA) is the authorized body for NEET.
