CBSE Class X Science exam is on March 25. For most of the class X students, this would be their last exam. After Mathematics, Science is considered as the second toughest. However, you can score very well in this exam, if you are well prepared. TCYonline experts have selected some important topics for the readers of Rediff.com to be revised from the chapters given in the NCERT textbook, for preparation.
DAY 1
