# Important Chapters of Physics for NEET 2018 with Syllabus

## Important Chapters for Physics in NEET 2018

NEET is one of the most important 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 Physics holds the 45 questions, students can’t finish all the chapters with deep studying as physics holds a vast course containing numerical and theory part.

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

Chapter-wise weightage of Physics:
