This book is the result of his extensive research in this field for the last 20 years. He qualified in 13 All India Level Competitive Examinations, some of which have been reckoned as the toughest and the most gruesome, alongside his research and writing work.

Apart from writing on mathematical subjects, Rajesh has a penchant for teaching mathematics and is a favorite teacher for his creative and entertaining ways of presenting the topic. His other books “Avoid Silly Mistakes in Mathematics” and " How to Memorize formulas in Mathematics" are very popular amongst students due to various innovative techniques methods explained in these books. This book is his third book.
