# Class 11th Physics

Physics is one of the critical subject of class 11th and therefore it is quite difficult to master in this particular subject. Physics is a subject which deals in the study of properties of matter and nature. It lays a foundation for various further studies of a studentâ€™s life. As it forms one of a core elements engineering and various other fields which class 11th Science students usually opt for, a proper understanding of concepts is necessary to qualify in this particular subject.
