I am Shantanu Sharma Graduated from IIT Roorkee (Completed in 2016) and I did my preparation for IIT-JEE 2012 from Kota Rajasthan.
If you want to get into top streams of any prestigious college then you need to go in the depth of the subject, just listen to each word of mine and make your Notes
So be Ready all the aspirants, here I am, I covered all the concepts of physics that can be asked in your exam, you don’t need to search for any book or any theory from anywhere, start learning with these video lectures, I am always with you, you can contact me anytime via What’s app (Number: +91-8287222487). Keep faith in yourself,

If you have any doubt, clear them in our online Doubt classes (Join our doubt classes with a free course at https://ideducation.in/free-course/ ).
You can put your questions in the notes n discussion section just below the video lecture.
