The unique feature of this book is problem-solving techniques that will help the students get top scores. The first part of this book deals with theory, examples, and exercises. In the examples, wherever it is required, I have shown the problem-solving techniques that will help you tackle a problem and solve it in the shortest way. In addition, I have included many problems that are generally not given in GMAT guidebooks. The purpose is to equip you to face any situation in the actual test. The second part of this book is designed as a workbook to help you apply the problem-solving techniques that you have studied in the first part. Every problem solving has a technique, and a particular technique can be applied to different types of problems. You will have to study and master them. A successful student will not only learn the techniques but also learn how to apply the appropriate technique for a particular problem.
