JEE Mains Physics Syllabus
JEE Mains Physics Syllabus – A Compilation of all the Topics

JEE Mains is the first phase of JEE and is conducted by CBSE every year to facilitate admissions into various undergraduate courses offered at NITs, IIITs, and other centrally funded institutes. As it is one of the toughest competitive exams in the world it is obvious that its preparation demands vigorous study.

It is very crucial to know about the syllabus before starting your preparations for JEE. The purpose of this separate article on JEE Mains Physics Syllabus is to let the student know about the content to be studied. Knowing the syllabus beforehand will help in better understanding of the topics relevant to JEE Mains 2018. The Physics Syllabus is itself further subdivided into two sections viz. Section A: 80% weightage (Theory Part) and Section B: 20% weightage (Experimental Skills).

All the chapters of Physics (Section A) are divided into 5 Units as follows:

  1. MECHANICS
  2. HEAT & THERMODYNAMICS
  3. ELECTROSTATICS & MAGNETISM
  4. CURRENT ELECTRICITY & EMI
  5. OPTICS & MODERN PHYSICS

Now, let us see the chapters falling under each unit.
