NEET Physics Chapter Wise Weightage 2020

Today, we will be giving an overview of Physics chapter wise weightage for NEET Exam. The Physics Section carries a weightage of 25% ie 45 questions from 180 questions will be from Physics. Physics is generally considered the toughest of all the 3 subjects. Keeping this in mind, we analyzed the question papers of the previous 3 years to get a weight-age, backed by data. In the previous two articles, we discussed chapter wise weightage for NEET Biology & Chemistry. 

Unit-wise weightage of NEET Physics

We have divided all the chapters of Physics into 5 units as given below:

  1. Mechanics (Class XI)
  2. Heat & Thermodynamics (Class XI)
  3. Electrostatics & Magnetism (Class XII)
  4. Current Electricity & EMI (Class XII)
  5. Optics & Modern Physics (Class XII)

The weightage of these units is given below:

UNITPrevious 3 year Analysis
Heat & Thermodynamics12.67
Electrostatics and Magnetism16.22
Current Electricity & EMI14.67
Optics & Modern Physics18.89

So as we can see, the highest weightage is that of Mechanics. Of course, this includes all the questions of Electrostatics which requires the knowledge of laws of motion or kinematics, which would actually take the weightage higher. So focus a lot on the mechanics part of class 11th for a clear understanding of the entire physics. Let's take a look at the chapter-wise weight in each of the units included in NEET Syllabus.

NEET Physics Chapter-wise weightage in Mechanics

Mechanics consist of the first 9 chapters of class XI from units & dimensions to Oscillations & waves. Check chapter-wise weight (the values given in each pie are the chapter-wise weight percentage out of total Physics marks) here. Mechanics is by far the most important unit of all and also include the most important chapters. It carries a maximum weightage of 37.6%. Among all the chapters, System of Particles and Rotational Motion carries the maximum weightage of 23.1%. Waves are the second most important chapter next to it. It carries a weightage of 18.3%.

NEET Physics Chapter-wise weight in Electrostatics & Magnetism

The first book of class XII consists of 8 chapters which are all inter-related. We have tried to broadly classify them into 2 Units, the first of which is Electrostatics & Magnetism.

Let's take a look at the chapter-wise weight in this case: Electrostatics and Magnetism carry a weightage of 16.2%. In this Section, Electrostatic Potential and Capacitance carries a weight-age of around 35.6%. It is then followed by Moving charges and Magnetism which carries a weigthtage of around 31.5%. Some very important topics from which the maximum number of numerals are expected for this year too are covered in this unit.

NEET 2019 Chapter-wise Weight of Optics & Modern Physics

This is the final unit and by the time you reach this you are exhausted and just want to finish the NEET Physics syllabus. However, if you went through the first graph, you would know that it has a huge weightage. Now, not to mention, this is perhaps the easiest unit to take care of considering all the questions asked here are completely formula based. This unit carries a weightage of 18.9%. The maximum number of questions were expected from the unit Dual Nature of Radiation and Matter, accordingly, this unit carries the maximum weightage of 35.3%. It is then followed by next important unit ie Wave optics which carries a weightage of around 29.4%.

The concept of Refraction and Total Internal Reflection, Refraction at Spherical Surfaces and by lenses are some of the important topics from the unit Ray Optics which carries a weightage of 27.1%Let's check out the chapter-wise weight of this unit.
