Indian Council of Secondary Education is also abbreviated as I.C.S.E. which is one of the best and famous non-governmental Board that serving quality education to their students across country. Physics is the most difficult subject to prepare for the exam as it includes various formula and mathematical derivations. So, it needs a little more attention to gain excellent marks in the Board Exams. The Objective of setting this ICSE Class 10 Physics Sample Papers is to give knowledge to the students of Board Exam about the pattern and the type of questions asked.

As a Graduate I am setting this ICSE Class 10 Physics Sample Papers for your help. Some help has been taken from previous year Board sample papers and I hope through this you will be able to get good marks in your Board Exams.
