Now its the time to buy the 10 year question paper for ICSE examination. Almost all the portions
are over for 10th graders. I suggest now every student of ICSE board to practice questions from the old sample papers and do the time bound tests. You will definitely improve your efficiency in coming days. Any questions or
doubts you can reach to me.
