Clever Study Preparation: Understanding the chapter-wise weightage allows you to concentrate on topics with higher marks in your exam. You can thus wisely allocate your study time to important topics instead of extending the time equally to every chapter. This will allow you to prepare in an organized manner and with a sense of purpose.
Effective Time Management: With weightage in hand, you can wisely plan your daily or weekly study schedule. You can give time for the high weightage chapters and quickly revise the less important chapters along with the previous one. This way, you can cover the curriculum promptly without any hassle.
Enhanced Revision Strategy: While doing revision using weightage, you understand which chapters require extra care. You can focus and study accordingly with important questions of the chapters. This systematic revision ultimately leads to better accuracy with maximum syllabus covered before the exam.
Chances of getting more marks: When you study according to chapter weightage, you first address the chapters with the most weightage. This will thus help to get more marks than you could possibly get if you unfortunately could not cover the whole syllabus. It will allow you to test your strengths in the exam.
Increases confidence: Understanding what to study for weightage and how much importance each chapter likely has helps in eliminating confusion, and unwanted stress.
