## NCERT Syllabus for Class 11 Physics – Free PDF Download

Physics is a crucial subject at the higher secondary stage of schooling. Students take Physics as a subject in Class 11 with the aim of pursuing their career ahead in this field. Physics students can go for further studies and research or pursue professional courses like medicine, engineering and technology after completing schooling. To achieve these aims, it’s required that students have a conceptual and strong understanding of Physics subject. So, from Class 11, students must start focussing on building the background for Physics. The first step into this is knowing the **NCERT Class 11 Physics Syllabus.** To help students with their studies, we have provided the NCERT Syllabus for Class 11 Physics.
