Solution for NEET

The first and most important thing for each student to do is to become acquainted with every syllabus topic. While planning ahead of time is beneficial, getting into the selected college will need clever and accurate study.

Keeping the competitive strain in mind, this essay will emphasize the critical components of preparing for NEET 2023. If you are into NEET Preparation Coaching Classes, ask your teachers to confirm those chapters.

Before we get into the specifics of the curriculum, let’s have a look at the chapters in each topic that are required to read and memorize to take the test.

NEET Physics Weightage by Chapter

The NEET Physics curriculum is made up of questions about theoretical topics that are simple to answer because they are largely definitions of various terminology. However, from a numerical standpoint, a wide range of queries are asked. As a result, applicants should be well-prepared for Physics, as it is a scoring component of NEET.

Chapters with the Most Weight

  • Their Poundage (Out Of 100)
  • 10% on Optics
  • 9% on Thermodynamics
  • 9% on Electrostatics
  • 9% on Electronic Devices
  • 9% on Current Electricity
  • 8% on Alternating Current & Electromagnetic Induction
  • 6% on Duality of Matter and Radiation

Important NEET 2023 Physics Chapters and Topics

Most candidates see physics as difficult owing to its numerical nature; nevertheless, with good study and determination, one may transform this area of the NEET test into a great chance because it is based on definitions, facts, and formulae.

Aspirants must understand the following topics while preparing for NEET because they make up the majority of the Physics portion for NEET 2023-


Electric Charges and Fields, Electrostatic Potential, and Capacitance should be prioritized.

The Rotational Motion System and the Motion of the System of Particles and Rigid Body Particles are significant subjects for this chapter.

Bulk Matter Properties

This chapter places high importance on the mechanical properties of solids, the mechanical properties of fluids, and the thermal properties of matter.

Waves and Oscillations

The general concept and function of oscillation and wave should be provided for brief numerical scoring.

Electricity in the Present

The entire chapter discusses critical numerical and theoretical components of NEET 2023.

Alternating Currents and Electromagnetic Induction

To score, this chapter requires a good comprehension of theory as well as numerical factors.


For this chapter, applicants must understand Ray Optics, Optical Instruments, and Wave Optics.

Electronic gadgets

Semiconductor Electronics is critical in this case since it is the subject of the majority of questions from this chapter.

NEET Chemistry Weightage by Chapter

Aspirants should be particularly careful in their preparation for Chemistry since it contains a lot of material on theories, reactions, statistics, and processes. To study, one must first split the course into Physical, Organic, and Inorganic Chemistry.

Now consider the weightage of these three portions:

This chapter will concentrate on ideal and non-ideal solutions, as well as ligature features.


This is an important chapter in the subject of Organic Chemistry that also contains the Ionization of acids and bases and the Solubility Equilibria of sparingly soluble salts.

Compounds of coordination

Another key Organic Chemistry chapter. Bonding in coordination compounds and coordination compound stability are important considerations.

The structure of atoms

The primary subjects to study in this chapter are the Bohr model for the hydrogen atom and the Quantum mechanical model of the atom.

Ethers, Phenols, and Alcohols

This chapter is extremely important in the Inorganic Chemistry portion.

Alcohol and phenol properties are essential for all NEET 2023 candidates to understand.

This chapter has a large number of scoring questions based on isomerism and key ideas in organic reaction mechanisms.

NEET Biology Weightage by Chapter

Here is the NEET Biology weightage distribution by chapter:

  • 20% on Human Physiology
  • 18% on Genetics and Evolution
  • 14% on Living World Diversity
  • 12% on Ecology and Environment

Important Biology Chapters and Topics for NEET 2023

  • The NEET questions are always drawn from the 11th and 12th-grade curriculums.

Some chapters and significant subjects for applicants to focus on are listed below-

Physiology of Man

All topics are important for learning. The diagrams in this chapter need more concentration.

Evolution And Genetics

This chapter discusses dihybrid crosses, linkage, codominance, pedigree analysis, genetic diseases, Darwinism and natural selection, and human evolution.

Environment and Ecology

This chapter needs applicants to understand the fundamentals of all environmental challenges, such as biogeochemical cycles and distinct environmental processes, population interactions, adaptations, and succession.


Processes and applications, BT cotton, RNAi, Human insulin, Gene therapy, and molecular diagnostics are all significant aspects of biotechnology to know.

Human Welfare and Biology
