This book is a reference material for students of Class 11 of CBSE and ISC boards (and may also benefit students of other boards with common syllabus). While solving problems, students often get stuck with formulas and have to navigate through many pages in their course book to reach them. This results in wastage of time, and, in the long run, a loss of interest in the subject.
This book gives the students one place where they can find all the formulas they need. Its small size makes it handy and can easily be carried without adding much weight to their already heavy bags. Students should spend 5-10 minutes every day and run their eyes through the formulas. To reiterate, this is only a reference book and not a substitute for the course books.
