Important Books to prepare JEE Main Physics Syllabus
All aspirants for JEE Main Examination must refer to certain basic Physics books in order to gain a better grasp over the subject. The texts mentioned below will aid all JEE aspirants in their preparation for the Examination.
- “Concept of Physics” Part I and Part I by H. C. Verma–
H. C. Verma is a Nuclear Physicist who is a professor in IIT Kanpur, and his book “Concept of Physics” has been the bestseller among the IIT JEE student circles for years. This is a two-volume set which explicates the fundamentals of theoretical physics in a comprehensive manner and as result is an absolute necessity for students of Physics. Its subject matter is ideal for IIT JEE Main, JEE Advanced as well as most State Level Engineering Entrance Exams. This book’s major asset however, is the exercises present in it. It has multiple short answer questions and MCQs of varying degrees of difficulty, as a result it prepares students for all possible Nation-wide Exams.
- “Understanding Physics” by D. C. Pandey-
This book is published by the Arihant Series specifically for JEE Main preparation. It is not for basic conceptual clarity in terms of theories in Physics, but is good for practice work. Once the students have honed their concepts and theories from H. C. Verma’s text, and have their groundwork done in advance, this book can be used to test their knowledge and their application of knowledge.

- “Problems in General Physics” by I. E. Irodov-
Irodov’s book is an excellent text for students interested in grappling with advanced theoretical Physics. But this is also a drawback in terms of JEE preparation because often topics explored in this book are beyond the textual syllabus of JEE Main. This is because Irodov’s text caters to a wide-range of audience and is not specifically intended for JEE aspirants. Yet this book is ideal for astute students who are eager to learn and are looking for a challenge. Some of the topics require substantial deliberation and problem-solving skills, and if students are ready to engage only with portions of the text which is within the JEE Main syllabus they can skip to the specific topics.
- “Fundamentals of Physics” by Halliday, Resnick and Walker-
Latest News Updates
If students are up to date with their fundamentals, from any of the 3 books mentioned above, they can use this as a reference book. As this text does not pander to the JEE aspirants and is geared towards students from American universities, it does not have much in-depth coverage of certain critical topics in the JEE syllabus.
These 4 books should be enough for JEE aspirants but apart from these, students should definitely solve the previous years’ question paxpers as well as several question banks.

Preparation Tips for JEE Main Physics Syllabus:
Candidates appearing for JEE Main have to be aware of the complete JEE Main Physics Syllabus so as to prepare well and get higher rankings. Focusing on the topics and preparing well keeping the syllabus as the base would help the candidate save time as well as has his/her attention on the important topics.
A major part of JEE Main consists of questions related to Physics, which makes it an important subject in terms of marks distribution. Having cleared the basics of what you have studied in class 11th and 12th is the key to scoring good in JEE Main. You should focus on scoring topics like Optics, Electricity & Magnetism, etc. and give extra attention to Kinematics and Particle dynamics. These are important parts of Mechanics and every year questions are asked from these topics.
According to the recent trend, Mechanics and Electricity Magnetism are the most important topics in terms of the number of questions. You should give ample amount of time to these topics.
Guidance and Mentor ship
As you are required to give your best in the limited time. You may face problems while going through different subject areas. A coaching institute, an experienced guide or a mentor will help a candidate a lot of the preparation.
Coaching institutes provide aspirants with study materials, preparation tests and doubt analysis for strong and weak areas of the candidate, which will help the aspirant in deciding their approach towards each section of the
subject. One of the important steps toward a preparation is to identify the subjects of your interests and weaknesses and make an individual strategy for them. You should keep asking the doubts to your mentor or even friends and make sure no doubts shall remain unanswered.
Time Management and Practice
It is advisable to take topic-wise sectional tests and practice several mock papers and actual previous year papers, in order to get familiar with the pattern and syllabus that is followed for JEE Main.
Division of Time is essential in order to make sure that you attempt all the sections of the entire paper properly. Managing time during preparation and during exam plays a very crucial role. Do not waste time on questions you don’t understand, move on to next question.
You should try to solve practice questions or numerical related to all the topics, practicing as much the candidate can from the past year question booklets and sample papers available on the internet and bookstores can
help a lot in understanding the format and get along with the questions of JEE Main.
Self-study is also very important during the preparation of the examination. You should try to reserve most of their precious time for self-study rather than engaging in tuition and coaching. It helps you to score good marks.
You should make separate notes of all the formulas of in each topic. For tackling the numerical and calculation based questions, you should revise important mathematical formula and have a grasp of class 10th Mathematics
as these questions required mathematical techniques.
Revision is very necessary before taking any examination or test, candidates should try to complete his/her syllabus 2 or 3 weeks before of the examination. Assign your last 2 weeks only for revision, it will definitely help candidates to obtain good marks.
To prepare for an exam, books are the best source as they enhance knowledge and provide insights about a topic but, you may often face plenty of problems to choose the right book. To lighten your burden, all the books mentioned below are chosen after careful research. Recommended Physics books for JEE Main.
