Disclaimer : I'm not sure if these topics are going to come in the examination. these are just some topics covered in different sample papers and school exams.

Don't get the wrong idea that if you study these topics, it is enough.

These are just some topics which are repeatedly asked and require more amount of revision. Kindly refrain from believing such things.

You still need to study the whole NCERT textbook. These are just some of the highlights. I REPEAT, DO NOT GET THE WRONG IDEA THAT THESE QUESTIONS ARE ENOUGH FOR THE EXAM.
