Hello Ashish,
It is a great choice to start chapter wise and most of the chapters are interconnected and without understanding the previous one it will be hard for you to get the next one.
You should focus on all the subjects and study hard in order to get good marks.
Yes if you will study chapter wise and grasping things properly with sufficient practice of numaricals, you will surely be able to get good marks(in physics) in your board exams.
Hope this will help.
