NTA has published NEET 2021 Physics Syllabus on its official website. Physics section carries 25% weightage out of 180 total marks of NEET 2021 exam. To check the NEET 2021 syllabus, you have to visit nta neet.nic.in.
Since NEET (UG) is now the only examination for admission in medical institutes in India, hence, the difficulty level might reduce. But to secure admission in a top-tier medical course, you have to solve NEET previous years question papers and sample papers with utmost dedication. It will also help you to understand the weightage of the questions of each section.
3 subjects are assessed in the examination – Physics, Chemistry, Biology. NCERT books of class 11th and 12th for each subject are extremely important while preparing for NEET 2021. Specifically, NEET 2021 Physics Syllabus is considered to be the toughest among the three subjects.
So, what should be the first step to start your NEET 2021 preparation? To begin with, aspirants should know the syllabus of each subject. Even though the NEET 2021 syllabus has not been announced this year, it is expected to be same as 2020.

NEET 2021 Physics Syllabus: Preparation Tips
NEET Physics syllabus is considered as difficult due to confusing patterns and also because it includes a wide range of scientific principles and numerical problems. Again, the top experts will not deny this fact. Hence, you should clear your concept first. Afterward, to cover the whole syllabus from 0 to 100, the students should follow a strategy.
Some Useful NEET 2021 Preparation Tips for Physics Syllabus
- Know NEET 2021 syllabus and exam pattern – Learn about what is going to be asked in the examinations. Check NEET 2021 Physics Syllabus and keep a print out of it as a task list accordingly. On the other hand, NEET 2021 Exam Pattern helps you to understand the intricacies of the exam.
- Focus on important concepts – The most important topics of NEET Physics Syllabus are – Mechanics, Heat, and Thermodynamics, Electrodynamics and also Modern Physics. This is based on past year trends. For instance, almost 50-60% of paper is set on these topics.
- Remember all formulae – Learning a formula is easy. However, learning a whole book of formulae is pretty difficult. Therefore, students must maintain a short book for these and keep revising the most important formulae accordingly.
- Practice old question papers – During the last few weeks of preparation, it is necessary to work on all the topics with equal importance. Therefore, take a pen and paper and solve the maximum old question papers.
- Create short notes – You must make notes of all the essential formulae, theorems and also principles when you are learning the topics for the first time. Consequently, this will help you during revision as short notes help in a quick go-through.
- Practice with Online Mock Tests – Take as many NEET mock tests as possible. Therefore, this will help you score well due to higher practice and also make you adapt to a computer-based environment. Moreover, mock analysis are available from each attempted test which will also help you to understand the weak topics
- Work on weak topics – Prioritize on most important topics of NEET Physics Syllabus and then plan for the less important ones. Moreover, working on mock will help in knowing the weak areas. Additionally, various websites provide topic-based tests to practice on various difficulty levels.
Best Books for NEET 2021 Preparation of Physics Syllabus
We have listed some important books to prepare aspirants for a strong base in NEET 2021 Physics syllabus subsequently. However, remember that this list is not exhaustive. You can refer to other books too if you find them useful.
|Physics for Medical Entrance Examinations||D.C. Pandey|
|Concepts of Physics||H.C. Verma|
|Fundamentals of Physics||Halliday, Resnick and Walker|
|Objective NCERT at your fingertips for NEET AIIMS- Physics||MTG Editorial Board|
