Central Board of Secondary Education or CBSE provides students a learning platform where they are able to learn concept in a fruitful manner. The board has its own curriculum that designs informative syllabus, sample papers and also provide study material to their students. Sample Papers are the best guide for the students to check their exam preparations if they includes all important topics that usually asked in the Exams. Physics is the easiest subject to prepare as it helps in learning basics of force, energy with relevant facts. Here we have tried to make available the CBSE 12th Physics Sample Paper, which covers topics like Electrostatics, Electricity, Electromagnetic Waves, Chemical Reactions etc. Thus start practicing to get excellent marks in your Board Exams.
