Question

do concepts of roation chapter apply in further physics of class 11 and 12 from jee point of view​ or due to shortage of time i can ignore it
???

Answer 1

although, u have less time , u may get it a look once

Answer 2

Rotation part is a very important part in physics, which covers a high weight age in the JEE exam. So if you'll skip that, it can cause harm to your marks. Though you don't have enough time right now, just get a look at it once.

That's what I would suggest
