UP Board Class 11 syllabus is a detailed set of content that covers all the topics taught in previous classes in a deeper way, which also makes it more extensive and tougher to cover for some students. The first step for any student to prepare for UP Board exams is to have a clear understanding of the syllabus.

Physics helps you understand how the world around us works in real life. From earthquakes, tsunamis, hurricanes, quarks,lungs and brains to can openers, black holes, light bulbs. It makes you curious to know more about the hidden knowledge in the world and widers your overall perspective.
