Class 11 CBSE Physics Syllabus

11th standard Physics is the most challenging area for most of the students because the concepts and their presentation is much advanced. The students must have skills to memorize, draw, calculate, write and reason the different aspects. The syllabus here assists in providing information on topics, sub topics, allotted time period, marks distribution for each chapter.  Different Teaching-learning strategies can be used ranging from simple talk-chalk (black board teaching), discussion, interactive sessions, and laboratory demonstration. Various visual media like power point presentation, video based lessons can also be used effectively.  Simply login to www.innoclazz.com and download the Class 11 physics syllabus.
