Important Chapters of Biology for NEET 2018 with Syllabus

Important Chapters for Biology in NEET 2018

 

NEET, one of the greatest examination for all medical students. Students tends to get confused when they have no idea about the NEET syllabus and the chapter-wise weightage. You are at the correct place, as Biology holds the most questions with most marks, students can’t finish all the chapters with deep studying as biology holds a vast course containing two different sections: Botany and Zoology.

To know more about Biology, you need to know about the syllabus with their chapter-wise weightage which is given below:
