Prepare Class 10 Science Chapter 1 Chemical Reactions and Equations from NCERT Textbook and then practice the questions given in the end of the chapter. At this stage MCQs are important for the revision of concepts and missing terms related to the chapters. If you read 5 times the same chapter from NCERT, every time you will get something new again. It means we have to revise the chapter again and again.
