![]() Chili Hot GMAT: 200 All-Star Problems to Get You a High Score on Your GMAT Exam Sale Price: $34.95 Eligible for free shipping!Availability: Usually ships in 24 hours See Reviews For This Product DescriptionFinalist in the 2010 International Book Awards ("College Guides" category)CHILI HOT GMAT helps readers develop the skills and mindset needed to score high on the GMAT exam. This book is based on a simple but powerful observation: Test-takers who score high on the GMAT exam do so primarily by understanding how to solve a finite number of the most important kinds of problems that appear on the GMAT. What are these important types of problems? The answer to this question is the basis of this book. In addition to comprehensive coverage of all six major problem types including Problem Solving, Data Sufficiency, Sentence Correction, Critical Reasoning, Reading Comprehension, and Analytical Writing, this manual also provides in-depth analysis of 194 multiple-choice problems and 6 essay questions. Each hand-selected problem comes with a classification, snapshot, and chili rating. Classification serves to identify each problem according to category or sub-category; snapshot highlights why that particular problem was chosen, including the underlying problem-solving principle or strategic approach; a chili rating helps candidates gauge the estimated difficulty level of a given problem. A single chili indicates that the difficulty level of a given problem is "mild" (500 to 600 difficulty level), two chilies spell "hot" (600 to 700 difficulty level), and three chilies signal "very hot" (700 or above difficulty level). By studying problems of varying difficulty, candidates will learn to maintain discipline on easy but tricky problems and also to exercise flexibility when deciding on multiple approaches and time-saving shortcuts for use in tackling harder, more involved problems. Note to readers: Chili Hot GMAT was formerly titled Ace the GMAT and is effectively a third edition book. |
