Class 11th plays a crucial role in the lives of students as it lays down the foundation and one cannot ignore this subject if he/she has to score good marks in 12th. Class 11th syllabus has a good weightage in competitive exams like JEE and NEET. An index is a roadmap to the book, listing places, names, and things in alphabetical order and giving the page numbers associated with each topic. Index plays a great role and saves a lot of time.

What is the index?

The index is the listing of names and things in alphabetical order and mentions the page number associated with each topic. Index plays a greater role in saving time as one can simply look at the index and find the required topic in less time. By looking at the index, students can easily find the topic and see the page number and then the required page can be opened. So, we can say that index provides quick access to the topics.

Class 11th Physics

Students have to choose the stream in class 11th and the correct combination of subjects. If he/she opts for medical or non-medical then physics is one of the main subjects one has to study for 2 years in school. Physics must not be memorized but understood in order to score well in the examination.

Importance of NCERT books

Although many books are available for class 11th Physics but NCERT books are the basic books and one must read the NCERT books. NCERT books are cheaper in comparison to other books and are affordable. All the topics are well explained in the book and practice questions are given at the end of every chapter and also between the chapters.
