Hemanth, Physics is arguably one of  the toughest sub-sections of Science and requires a lot of hardwork in order to be good at it. If you aren't good at it, then firstly you should try to remove its fear from your mind as when you are not good at something, you try to escape from it by trying to devote less time to it and more time to other subjects rather you should devote the most time to Physics and try to read the NCERT Class 11 and Class 12 which would improve the basics of the subject and if your basics are strong, then you would be able to understand the further theory more easily. Also,can  try to watch YouTube videos on the topics which you face problems in as in my opinion, there are some really top notch educators available on that platform. Also, Physics is a subject which demands regularity in both the theory and its application in the form of numericals, so you should try to go through the NCERT and your reference book at least twice or thrice in order to be able to comprehend the theory properly.

Therefore, it is not a big problem that you aren't too good at Physics, infact most of the people aren't initially good at it, you just need to work continuously on the basics and the applications of theory and try to solve as many numericals as you can which would not only improve your understanding but also give you the confidence to be able to manage the subject properly.

Hello Hemanth

No need to worry dear , physics is totally a conceptual subject so you cannot excel in it unless you master it's concepts, so what you should do is go through the theory of the chapter well and take the help of your teacher to understand the topics which you couldn't understand  from books or you can even use YouTube to learn concepts and after completing each chapter you should learn how to apply the learn concepts by going through the solved examples and after that you should solve questions yourself, you should do the same for every chapter and you should revise concepts and important formula at regular interval . Follow this , technique and soon you will be good at physics

Thank you

To master over physics you should focus on the concepts as well as the mathematics behind it, basics of calculus and vector is essential to understand the physics so if you are not comfortable with t then you should give some time to make it clear.

Solving problems also proved to be efficient way to learn physics, so solve some numerical on each topic so that you learn concepts along with reading and solving the problems.
