However, the techniques that you shall find in this book have been tested and used (not only by the author but by countless other people) in examinations time and again.Many techniques mentioned in other books are pretty impractical and sometimes completely unusable. This book is not a package of magic. It is rather a package of methods that if practiced and persevered with can churn up magical results! This book could be a great resource for various competitive examinations and students in middle and senior school. It could help the reader in myriad ways depending upon his or her needs and scope for practice. At the same time one could figure out as to which technique would work for one and which would not, again depending upon one’s set of circumstances and needs. By reading this book, the students will be able to:(a) learn quicker methods by observing some simple techniques;compare various techniques available on each topic;(b) know the limitations of each technique;(c) save some precious minutes in various competitive and school examinations by employing the quick calculation techniques;(d) develop their own tools in the field of quick calculations.

    We're not supposed to. Ironically, if we could literally live every single day that time and space have left, our lives would be almost meaningless. It's the end of lives that cause them to matter. But your life, short as it is -- and perhaps because it's short -- can have more meaning and more effect on other people than you can possibly imagine… if you chose to let it. The end of your life is not the end. Not unless you let it be, through your actions and inactions during the time you're alive. The end of your life -- thanks to the turbulence you leave behind you in the stream of time -- is the beginning.
