Important Chapters for Chemistry in NEET 2018

 

NEET, one of the toughest examination for all medical aspirants. 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 Chemistry holds the 45 questions, students can’t finish all the chapters with deep studying as chemistry holds a vast course containing numerical, reactions and theory part.

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