Hello,

Important question is not available. You have to study in whole. You can't skip any part as it is not known from which part questions will be asked. So overall preparation is advised.

Chapters are easy when you read them multiple time. It will make your concept basics clear and increase your interest. You have to solve numericals as it will be asked in exam. So first solve numericals in example and then go to end chapter excercise.

Hope it helps!
